Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide basis for identifying the adverse events that appear to be related to drug use and for approximating rates.Of the celecoxib-treated patients in the pre-marketing controlled clinical trials, approximately 4,250 were patients with OA, approximately 2,100 were patients with RA, and approximately 1,050 were patients with post-surgical pain. More than 8,500 patients received total daily dose of celecoxib of 200 mg (100 mg twice daily or 200 mg once daily) or more, including more than 400 treated at 800 mg (400 mg twice daily). Approximately 3,900 patients received celecoxib at these doses for months or more; approximately 2,300 of these have received it for year or more and 124 of these have received it for years or more.Pre-marketing Controlled Arthritis TrialsTable lists all adverse events, regardless of causality, occurring in >=2% of patients receiving celecoxib from 12 controlled studies conducted in patients with OA or RA that included placebo and/or positive control group. Since these 12 trials were of different durations, and patients in the trials may not have been exposed for the same duration of time, these percentages do not capture cumulative rates of occurrence.Table 1: Adverse Events Occurring in >=2% of Celecoxib Patients from Pre-marketing Controlled Arthritis Trials CBX Placebo NAP DCF IBU N=4146 N=1864 N=1366 N=387 N=345 Gastrointestinal Abdominal Pain 4.1% 2.8% 7.7% 9.0% 9.0% Diarrhea 5.6% 3.8% 5.3% 9.3% 5.8% Dyspepsia 8.8% 6.2% 12.2% 10.9% 12.8% Flatulence 2.2% 1.0% 3.6% 4.1% 3.5% Nausea 3.5% 4.2% 6.0% 3.4% 6.7% Body as whole Back Pain 2.8% 3.6% 2.2% 2.6% 0.9% Peripheral Edema 2.1% 1.1% 2.1% 1.0% 3.5% Injury-Accidental 2.9% 2.3% 3.0% 2.6% 3.2% Central, Peripheral Nervous system Dizziness 2.0% 1.7% 2.6% 1.3% 2.3% Headache 15.8% 20.2% 14.5% 15.5% 15.4% Psychiatric Insomnia 2.3% 2.3% 2.9% 1.3% 1.4% Respiratory Pharyngitis 2.3% 1.1% 1.7% 1.6% 2.6% Rhinitis 2.0% 1.3% 2.4% 2.3% 0.6% Sinusitis 5.0% 4.3% 4.0% 5.4% 5.8% Upper Respiratory Infection 8.1% 6.7% 9.9% 9.8% 9.9% Skin Rash 2.2% 2.1% 2.1% 1.3% 1.2% CBX Celecoxib 100 mg to 200 mg twice daily or 200 mg once daily; NAP Naproxen 500 mg twice daily; DCF Diclofenac 75 mg twice daily; IBU Ibuprofen 800 mg three times daily.In placebo- or active-controlled clinical trials, the discontinuation rate due to adverse events was 7.1% for patients receiving celecoxib and 6.1% for patients receiving placebo. Among the most common reasons for discontinuation due to adverse events in the celecoxib treatment groups were dyspepsia and abdominal pain (cited as reasons for discontinuation in 0.8% and 0.7% of celecoxib patients, respectively). Among patients receiving placebo, 0.6% discontinued due to dyspepsia and 0.6% withdrew due to abdominal pain.The following adverse reactions occurred in 0.1% to 1.9% of patients treated with celecoxib (100 mg to 200 mg twice daily or 200 mg once daily):Gastrointestinal: Constipation, diverticulitis, dysphagia, eructation, esophagitis, gastritis, gastroenteritis, gastroesophageal reflux, hemorrhoids, hiatal hernia, melena, dry mouth, stomatitis, tenesmus, vomitingCardiovascular: Aggravated hypertension, angina pectoris, coronary artery disorder, myocardial infarctionGeneral: Hypersensitivity, allergic reaction, chest pain, cyst NOS, edema generalized, face edema, fatigue, fever, hot flushes, influenza-like symptoms, pain, peripheral painCentral, peripheral nervous system: Leg cramps, hypertonia, hypoesthesia, migraine, paresthesia, vertigoHearing and vestibular: Deafness, tinnitusHeart rate and rhythm: Palpitation, tachycardiaLiver and biliary: Hepatic enzyme increased (including SGOT increased, SGPT increased)Metabolic and nutritional: blood urea nitrogen (BUN) increased, creatine phosphokinase (CPK) increased, hypercholesterolemia, hyperglycemia, hypokalemia, NPN increased, creatinine increased, alkaline phosphatase increased, weight increasedMusculoskeletal: Arthralgia, arthrosis, myalgia, synovitis, tendinitisPlatelets (bleeding or clotting): Ecchymosis, epistaxis, thrombocythemia,Psychiatric: Anorexia, anxiety, appetite increased, depression, nervousness, somnolenceHemic: AnemiaRespiratory: Bronchitis, bronchospasm, bronchospasm aggravated, cough, dyspnea, laryngitis, pneumoniaSkin and appendages: Alopecia, dermatitis, photosensitivity reaction, pruritus, rash erythematous, rash maculopapular, skin disorder, skin dry, sweating increased, urticariaApplication site disorders: Cellulitis, dermatitis contactUrinary: Albuminuria, cystitis, dysuria, hematuria, micturition frequency, renal calculusThe following serious adverse events (causality not evaluated) occurred in <0.1% of patients:Cardiovascular: Syncope, congestive heart failure, ventricular fibrillation, pulmonary embolism, cerebrovascular accident, peripheral gangrene, thrombophlebitisGastrointestinal: Intestinal obstruction, intestinal perforation, gastrointestinal bleeding, colitis with bleeding, esophageal perforation, pancreatitis, ileusGeneral: Sepsis, sudden deathLiver and biliary: CholelithiasisHemic and lymphatic: ThrombocytopeniaNervous: Ataxia, suicide [see Drug Interactions (7)] Renal: Acute renal failureThe Celecoxib Long-Term Arthritis Safety Study [see Clinical Studies (14.7)] Hematological Events: The incidence of clinically significant decreases in hemoglobin (2 g/dL) was lower in patients on celecoxib 400 mg twice daily (0.5%) compared to patients on either diclofenac 75 mg twice daily (1.3%) or ibuprofen 800 mg three times daily 1.9%. The lower incidence of events with celecoxib was maintained with or without aspirin use [see Clinical Pharmacology (12.2)].Withdrawals/Serious Adverse Events: Kaplan-Meier cumulative rates at months for withdrawals due to adverse events for celecoxib, diclofenac and ibuprofen were 24%, 29%, and 26%, respectively. Rates for serious adverse events (i.e., causing hospitalization or felt to be life-threatening or otherwise medically significant), regardless of causality, were not different across treatment groups (8%, 7%, and 8%, respectively).Juvenile Rheumatoid Arthritis StudyIn 12-week, double-blind, active-controlled study, 242 JRA patients years to 17 years of age were treated with celecoxib or naproxen; 77 JRA patients were treated with celecoxib mg/kg twice daily, 82 patients were treated with celecoxib mg/kg twice daily, and 83 patients were treated with naproxen 7.5 mg/kg twice daily. The most commonly occurring (>=5%) adverse events in celecoxib treated patients were headache, fever (pyrexia), upper abdominal pain, cough, nasopharyngitis, abdominal pain, nausea, arthralgia, diarrhea, and vomiting. The most commonly occurring (>=5%) adverse experiences for naproxen-treated patients were headache, nausea, vomiting, fever, upper abdominal pain, diarrhea, cough, abdominal pain, and dizziness (Table 2). Compared with naproxen, celecoxib at doses of and mg/kg twice daily had no observable deleterious effect on growth and development during the course of the 12-week double-blind study. There was no substantial difference in the number of clinical exacerbations of uveitis or systemic features of JRA among treatment groups.In 12-week, open-label extension of the double-blind study described above, 202 JRA patients were treated with celecoxib mg/kg twice daily. The incidence of adverse events was similar to that observed during the double-blind study; no unexpected adverse events of clinical importance emerged.Table 2: Adverse Events Occurring in >=5% of JRA Patients in Any Treatment Group, by System Organ Class (% of patients with events) All Doses Twice Daily Celecoxib Celecoxib Naproxen System Organ Class mg/kg mg/kg 7.5 mg/kg Preferred Term N=77 N=82 N=83 Any Event 64 70 72 Eye Disorders 5 Gastrointestinal 26 24 36 Abdominal pain NOS 7 Abdominal pain upper 6 10 Vomiting NOS 6 11 Diarrhea NOS 4 Nausea 4 11 General 13 11 18 Pyrexia 9 11 Infections 25 20 27 Nasopharyngitis 6 Injury and Poisoning 6 Investigations 11 Musculoskeletal 10 17 Arthralgia 7 Nervous System 17 11 21 Headache NOS 13 10 16 Dizziness (excl vertigo) 1 Respiratory 15 15 Cough 7 Skin Subcutaneous 10 18 Abnormal laboratory tests, which include: Prolonged activated partial thromboplastin time, Bacteriuria NOS present, Blood creatine phosphokinase increased, Blood culture positive, Blood glucose increased, Blood pressure increased, Blood uric acid increased, Hematocrit decreased, Hematuria present, Hemoglobin decreased, Liver function tests NOS abnormal, Proteinuria present, Transaminase NOS increased, Urine analysis abnormal NOSOther Pre-Approval StudiesAdverse Events from Ankylosing Spondylitis Studies: total of 378 patients were treated with celecoxib in placebo- and active-controlled AS studies. Doses up to 400 mg once daily were studied. The types of adverse events reported in the AS studies were similar to those reported in the OA/RA studies.Adverse Events from Analgesia and Dysmenorrhea Studies: Approximately 1,700 patients were treated with celecoxib in analgesia and dysmenorrhea studies. All patients in post-oral surgery pain studies received single dose of study medication. Doses up to 600 mg/day of celecoxib were studied in primary dysmenorrhea and post-orthopedic surgery pain studies. The types of adverse events in the analgesia and dysmenorrhea studies were similar to those reported in arthritis studies. The only additional adverse event reported was post-dental extraction alveolar osteitis (dry socket) in the post-oral surgery pain studies.The APC and PreSAP TrialsAdverse reactions from long-term, placebo-controlled polyp prevention studies: Exposure to celecoxib in the APC and PreSAP trials was 400 mg to 800 mg daily for up to years [see Clinical Studies (14.7) ].Some adverse reactions occurred in higher percentages of patients than in the arthritis pre-marketing trials (treatment durations up to 12 weeks; see Adverse events from celecoxib pre-marketing controlled arthritis trials, above). The adverse reactions for which these differences in patients treated with celecoxib were greater as compared to the arthritis pre-marketing trials were as follows: Celecoxib (400 to 800 mg daily) Placebo = 2285 N=1303 Diarrhea 10.5% 7.0% Gastroesophageal reflux disease 4.7% 3.1% Nausea 6.8% 5.3% Vomiting 3.2% 2.1% Dyspnea 2.8% 1.6% Hypertension 12.5% 9.8% Nephrolithiasis 2.1% 0.8%The following additional adverse reactions occurred in >=0.1% and <1% of patients taking celecoxib, at an incidence greater than placebo in the long-term polyp prevention studies, and were either not reported during the controlled arthritis pre-marketing trials or occurred with greater frequency in the long-term, placebo-controlled polyp prevention studies:Nervous system disorders: Cerebral infarctionEye disorders: Vitreous floaters, conjunctival hemorrhageEar and labyrinth: LabyrinthitisCardiac disorders: Angina unstable, aortic valve incompetence, coronary artery atherosclerosis, sinus bradycardia, ventricular hypertrophyVascular disorders: Deep vein thrombosisReproductive system and breast disorders: Ovarian cystInvestigations: Blood potassium increased, blood sodium increased, blood testosterone decreasedInjury, poisoning, and procedural complications: Epicondylitis, tendon rupture. 6.2 Postmarketing Experience. The following adverse reactions have been identified during post approval use of celecoxib. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposureCardiovascular: Vasculitis, deep venous thrombosisGeneral: Anaphylactoid reaction, angioedemaLiver and biliary: Liver necrosis, hepatitis, jaundice, hepatic failureHemic and lymphatic: Agranulocytosis, aplastic anemia, pancytopenia, leucopeniaMetabolic: Hypoglycemia, hyponatremiaNervous: Aseptic meningitis, ageusia, anosmia, fatal intracranial hemorrhageRenal: Interstitial nephritis.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. CarcinogenesisCelecoxib was not carcinogenic in Sprague-Dawley rats given oral doses up to 200 mg/kg for males and 10 mg/kg for females (approximately 2- to 4-times the human exposure as measured by the AUC0-24 at 200 mg twice daily) or in mice given oral doses up to 25 mg/kg for males and 50 mg/kg for females (approximately equal to human exposure as measured by the AUC0-24 at 200 mg twice daily) for two years.MutagenesisCelecoxib was not mutagenic in an Ames test and mutation assay in Chinese hamster ovary (CHO) cells, nor clastogenic in chromosome aberration assay in CHO cells and an in vivo micronucleus test in rat bone marrow.Impairment of FertilityCelecoxib had no effect on male or female fertility or male reproductive function in rats at oral doses up to 600 mg/kg/day (approximately 11-times human exposure at 200 mg twice daily based on the AUC0-24). At >=50 mg/kg/day (approximately 6-times human exposure based on the AUC0-24 at 200 mg twice daily) there was increased preimplantation loss.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Celecoxib has analgesic, anti-inflammatory, and antipyretic properties.The mechanism of action of celecoxib is believed to be due to inhibition of prostaglandin synthesis, primarily via inhibition of COX-2.Celecoxib is potent inhibitor of prostaglandin synthesis in vitro. Celecoxib concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Since celecoxib is an inhibitor of prostaglandin synthesis, its mode of action may be due to decrease of prostaglandins in peripheral tissues.. 12.2 Pharmacodynamics. PlateletsIn clinical trials using normal volunteers, celecoxib at single doses up to 800 mg and multiple doses of 600 mg twice daily for up to days duration (higher than recommended therapeutic doses) had no effect on reduction of platelet aggregation or increase in bleeding time. Because of its lack of platelet effects, celecoxib is not substitute for aspirin for cardiovascular prophylaxis. It is not known if there are any effects of celecoxib on platelets that may contribute to the increased risk of serious cardiovascular thrombotic adverse events associated with the use of celecoxib.Fluid RetentionInhibition of PGE2 synthesis may lead to sodium and water retention through increased reabsorption in the renal medullary thick ascending loop of Henle and perhaps other segments of the distal nephron. In the collecting ducts, PGE2 appears to inhibit water reabsorption by counteracting the action of antidiuretic hormone.. 12.3 Pharmacokinetics. Celecoxib exhibits dose-proportional increase in exposure after oral administration up to 200 mg twice daily and less than proportional increase at higher doses. It has extensive distribution and high protein binding. It is primarily metabolized by CYP2C9 with half-life of approximately 11 hours.AbsorptionPeak plasma levels of celecoxib occur approximately hours after an oral dose. Under fasting conditions, both peak plasma levels (Cmax) and area under the curve (AUC) are roughly dose-proportional up to 200 mg twice daily; at higher doses there are less than proportional increases in Cmax and AUC (see Food Effects). Absolute bioavailability studies have not been conducted. With multiple dosing, steady-state conditions are reached on or before Day 5. The pharmacokinetic parameters of celecoxib in group of healthy subjects are shown in Table 4.Table 4: Summary of Single Dose (200 mg) Disposition Kinetics of Celecoxib in Healthy Subjects1 Mean (%CV) PK Parameter Values max ng/mL max hr Effective 1/2 hr ss /F, CL/F, L/hr 705 (38) 2.8 (37) 11.2 (31) 429 (34) 27.7 (28) Subjects under fasting conditions (n=36, 19-52 yrs.)Food EffectsWhen celecoxib capsules were taken with high fat meal, peak plasma levels were delayed for about to hours with an increase in total absorption (AUC) of 10% to 20%. Under fasting conditions, at doses above 200 mg, there is less than proportional increase in Cmax and AUC, which is thought to be due to the low solubility of the drug in aqueous media.Coadministration of celecoxib capsules with an aluminum- and magnesium-containing antacids resulted in reduction in plasma celecoxib concentrations with decrease of 37% in Cmax and 10% in AUC. Celecoxib capsules, at doses up to 200 mg twice daily, can be administered without regard to timing of meals. Higher doses (400 mg twice daily) should be administered with food to improve absorption.In healthy adult volunteers, the overall systemic exposure (AUC) of celecoxib was equivalent when celecoxib was administered as intact capsule or capsule contents sprinkled on applesauce. There were no significant alterations in Cmax, Tmax or t1/2 after administration of capsule contents on applesauce [see Dosage and Administration (2) ].DistributionIn healthy subjects, celecoxib is highly protein bound (~97%) within the clinical dose range. In vitro studies indicate that celecoxib binds primarily to albumin and, to lesser extent, 1-acid glycoprotein. The apparent volume of distribution at steady state (Vss/F) is approximately 400 L, suggesting extensive distribution into the tissues. Celecoxib is not preferentially bound to red blood cells.EliminationMetabolismCelecoxib metabolism is primarily mediated via CYP2C9. Three metabolites, primary alcohol, the corresponding carboxylic acid and its glucuronide conjugate, have been identified in human plasma. These metabolites are inactive as COX-1 or COX-2 inhibitors.ExcretionCelecoxib is eliminated predominantly by hepatic metabolism with little (<3%) unchanged drug recovered in the urine and feces. Following single oral dose of radiolabeled drug, approximately 57% of the dose was excreted in the feces and 27% was excreted into the urine. The primary metabolite in both urine and feces was the carboxylic acid metabolite (73% of dose) with low amounts of the glucuronide also appearing in the urine. It appears that the low solubility of the drug prolongs the absorption process making terminal half-life (t1/2) determinations more variable. The effective half-life is approximately 11 hours under fasted conditions. The apparent plasma clearance (CL/F) is about 500 mL/min.Specific PopulationsGeriatricAt steady state, elderly subjects (over 65 years old) had 40% higher Cmax and 50% higher AUC compared to the young subjects. In elderly females, celecoxib Cmax and AUC are higher than those for elderly males, but these increases are predominantly due to lower body weight in elderly females. Dose adjustment in the elderly is not generally necessary. However, for patients of less than 50 kg in body weight, initiate therapy at the lowest recommended dose [see Use in Specific Populations (8.5) ].PediatricThe steady state pharmacokinetics of celecoxib administered as an investigational oral suspension was evaluated in 152 JRA patients years to 17 years of age weighing >=10 kg with pauciarticular or polyarticular course JRA and in patients with systemic onset JRA. Population pharmacokinetic analysis indicated that the oral clearance (unadjusted for body weight) of celecoxib increases less than proportionally to increasing weight, with 10 kg and 25 kg patients predicted to have 40% and 24% lower clearance, respectively, compared with 70 kg adult RA patient.Twice-daily administration of 50 mg capsules to JRA patients weighing >=12 to <=25 kg and 100 mg capsules to JRA patients weighing 25 kg should achieve plasma concentrations similar to those observed in clinical trial that demonstrated the non-inferiority of celecoxib to naproxen 7.5 mg/kg twice daily [see Dosage and Administration (2.4)]. Celecoxib has not been studied in JRA patients under the age of years, in patients with body weight less than 10 kg (22 lbs), or beyond 24 weeks.RaceMeta-analysis of pharmacokinetic studies has suggested an approximately 40% higher AUC of celecoxib in Blacks compared to Caucasians. The cause and clinical significance of this finding is unknown.Hepatic ImpairmentA pharmacokinetic study in subjects with mild (Child-Pugh Class A) and moderate (Child-Pugh Class B) hepatic impairment has shown that steady-state celecoxib AUC is increased about 40% and 180%, respectively, above that seen in healthy control subjects. Therefore, the daily recommended dose of celecoxib capsules should be reduced by approximately 50% in patients with moderate (Child-Pugh Class B) hepatic impairment. Patients with severe hepatic impairment (Child-Pugh Class C) have not been studied. The use of celecoxib in patients with severe hepatic impairment is not recommended [see Dosage and Administration (2.7) and Use in Specific Populations (8.6) ].Renal ImpairmentIn cross-study comparison, celecoxib AUC was approximately 40% lower in patients with chronic renal insufficiency (GFR 35-60 mL/min) than that seen in subjects with normal renal function. No significant relationship was found between GFR and celecoxib clearance. Patients with severe renal insufficiency have not been studied. Similar to other NSAIDs, celecoxib is not recommended in patients with severe renal insufficiency [see Warnings and Precautions (5.6) ].Drug Interaction StudiesIn vitro studies indicate that celecoxib is not an inhibitor of cytochrome P450 2C9, 2C19 or 3A4.In vivo studies have shown the following:AspirinWhen NSAIDs were administered with aspirin, the protein binding of NSAIDs were reduced, although the clearance of free NSAID was not altered. The clinical significance of this interaction is not known. See Table for clinically significant drug interactions of NSAIDs with aspirin [see Drug Interactions (7)].LithiumIn study conducted in healthy subjects, mean steady-state lithium plasma levels increased approximately 17% in subjects receiving lithium 450 mg twice daily with celecoxib capsules 200 mg twice daily as compared to subjects receiving lithium alone [see Drug Interactions (7) ].FluconazoleConcomitant administration of fluconazole at 200 mg once daily resulted in two-fold increase in celecoxib plasma concentration. This increase is due to the inhibition of celecoxib metabolism via P450 2C9 by fluconazole [see Drug Interactions (7) ].Other DrugsThe effects of celecoxib on the pharmacokinetics and/or pharmacodynamics of glyburide, ketoconazole, [see Drug Interactions (7) ], phenytoin, and tolbutamide have been studied in vivo and clinically important interactions have not been found.. 12.5 Pharmacogenomics. CYP2C9 activity is reduced in individuals with genetic polymorphisms that lead to reduced enzyme activity, such as those homozygous for the CYP2C92 and CYP2C93 polymorphisms. Limited data from published reports that included total of subjects with the homozygous CYP2C93/3 genotype showed celecoxib systemic levels that were 3- to 7-fold higher in these subjects compared to subjects with CYP2C91/1 or I/3 genotypes. The pharmacokinetics of celecoxib have not been evaluated in subjects with other CYP2C9 polymorphisms, such as 2, 5, 6, and 11. It is estimated that the frequency of the homozygous 3/3 genotype is 0.3% to 1.0% in various ethnic groups [see Dosage and Administration (2.7) Use in Specific Populations (8.8) ].

Among the most common reasons for discontinuation due to adverse events in the celecoxib treatment groups were dyspepsia and abdominal pain (cited as reasons for discontinuation in 0.8% and 0.7% of celecoxib patients, respectively). Among patients receiving placebo, 0.6% discontinued due to dyspepsia and 0.6% withdrew due to abdominal pain.The following adverse reactions occurred in 0.1% to 1.9% of patients treated with celecoxib (100 mg to 200 mg twice daily or 200 mg once daily):Gastrointestinal: Constipation, diverticulitis, dysphagia, eructation, esophagitis, gastritis, gastroenteritis, gastroesophageal reflux, hemorrhoids, hiatal hernia, melena, dry mouth, stomatitis, tenesmus, vomitingCardiovascular: Aggravated hypertension, angina pectoris, coronary artery disorder, myocardial infarctionGeneral: Hypersensitivity, allergic reaction, chest pain, cyst NOS, edema generalized, face edema, fatigue, fever, hot flushes, influenza-like symptoms, pain, peripheral painCentral, peripheral nervous system: Leg cramps, hypertonia, hypoesthesia, migraine, paresthesia, vertigoHearing and vestibular: Deafness, tinnitusHeart rate and rhythm: Palpitation, tachycardiaLiver and biliary: Hepatic enzyme increased (including SGOT increased, SGPT increased)Metabolic and nutritional: blood urea nitrogen (BUN) increased, creatine phosphokinase (CPK) increased, hypercholesterolemia, hyperglycemia, hypokalemia, NPN increased, creatinine increased, alkaline phosphatase increased, weight increasedMusculoskeletal: Arthralgia, arthrosis, myalgia, synovitis, tendinitisPlatelets (bleeding or clotting): Ecchymosis, epistaxis, thrombocythemia,Psychiatric: Anorexia, anxiety, appetite increased, depression, nervousness, somnolenceHemic: AnemiaRespiratory: Bronchitis, bronchospasm, bronchospasm aggravated, cough, dyspnea, laryngitis, pneumoniaSkin and appendages: Alopecia, dermatitis, photosensitivity reaction, pruritus, rash erythematous, rash maculopapular, skin disorder, skin dry, sweating increased, urticariaApplication site disorders: Cellulitis, dermatitis contactUrinary: Albuminuria, cystitis, dysuria, hematuria, micturition frequency, renal calculusThe following serious adverse events (causality not evaluated) occurred in <0.1% of patients:Cardiovascular: Syncope, congestive heart failure, ventricular fibrillation, pulmonary embolism, cerebrovascular accident, peripheral gangrene, thrombophlebitisGastrointestinal: Intestinal obstruction, intestinal perforation, gastrointestinal bleeding, colitis with bleeding, esophageal perforation, pancreatitis, ileusGeneral: Sepsis, sudden deathLiver and biliary: CholelithiasisHemic and lymphatic: ThrombocytopeniaNervous: Ataxia, suicide [see Drug Interactions (7)] Renal: Acute renal failureThe Celecoxib Long-Term Arthritis Safety Study [see Clinical Studies (14.7)] Hematological Events: The incidence of clinically significant decreases in hemoglobin (2 g/dL) was lower in patients on celecoxib 400 mg twice daily (0.5%) compared to patients on either diclofenac 75 mg twice daily (1.3%) or ibuprofen 800 mg three times daily 1.9%. The lower incidence of events with celecoxib was maintained with or without aspirin use [see Clinical Pharmacology (12.2)].Withdrawals/Serious Adverse Events: Kaplan-Meier cumulative rates at months for withdrawals due to adverse events for celecoxib, diclofenac and ibuprofen were 24%, 29%, and 26%, respectively. Rates for serious adverse events (i.e., causing hospitalization or felt to be life-threatening or otherwise medically significant), regardless of causality, were not different across treatment groups (8%, 7%, and 8%, respectively).Juvenile Rheumatoid Arthritis StudyIn 12-week, double-blind, active-controlled study, 242 JRA patients years to 17 years of age were treated with celecoxib or naproxen; 77 JRA patients were treated with celecoxib mg/kg twice daily, 82 patients were treated with celecoxib mg/kg twice daily, and 83 patients were treated with naproxen 7.5 mg/kg twice daily. The most commonly occurring (>=5%) adverse events in celecoxib treated patients were headache, fever (pyrexia), upper abdominal pain, cough, nasopharyngitis, abdominal pain, nausea, arthralgia, diarrhea, and vomiting. The most commonly occurring (>=5%) adverse experiences for naproxen-treated patients were headache, nausea, vomiting, fever, upper abdominal pain, diarrhea, cough, abdominal pain, and dizziness (Table 2). Compared with naproxen, celecoxib at doses of and mg/kg twice daily had no observable deleterious effect on growth and development during the course of the 12-week double-blind study. There was no substantial difference in the number of clinical exacerbations of uveitis or systemic features of JRA among treatment groups.In 12-week, open-label extension of the double-blind study described above, 202 JRA patients were treated with celecoxib mg/kg twice daily. The incidence of adverse events was similar to that observed during the double-blind study; no unexpected adverse events of clinical importance emerged.Table 2: Adverse Events Occurring in >=5% of JRA Patients in Any Treatment Group, by System Organ Class (% of patients with events) All Doses Twice Daily Celecoxib Celecoxib Naproxen System Organ Class mg/kg mg/kg 7.5 mg/kg Preferred Term N=77 N=82 N=83 Any Event 64 70 72 Eye Disorders 5 Gastrointestinal 26 24 36 Abdominal pain NOS 7 Abdominal pain upper 6 10 Vomiting NOS 6 11 Diarrhea NOS 4 Nausea 4 11 General 13 11 18 Pyrexia 9 11 Infections 25 20 27 Nasopharyngitis 6 Injury and Poisoning 6 Investigations 11 Musculoskeletal 10 17 Arthralgia 7 Nervous System 17 11 21 Headache NOS 13 10 16 Dizziness (excl vertigo) 1 Respiratory 15 15 Cough 7 Skin Subcutaneous 10 18 Abnormal laboratory tests, which include: Prolonged activated partial thromboplastin time, Bacteriuria NOS present, Blood creatine phosphokinase increased, Blood culture positive, Blood glucose increased, Blood pressure increased, Blood uric acid increased, Hematocrit decreased, Hematuria present, Hemoglobin decreased, Liver function tests NOS abnormal, Proteinuria present, Transaminase NOS increased, Urine analysis abnormal NOSOther Pre-Approval StudiesAdverse Events from Ankylosing Spondylitis Studies: total of 378 patients were treated with celecoxib in placebo- and active-controlled AS studies. Doses up to 400 mg once daily were studied. The types of adverse events reported in the AS studies were similar to those reported in the OA/RA studies.Adverse Events from Analgesia and Dysmenorrhea Studies: Approximately 1,700 patients were treated with celecoxib in analgesia and dysmenorrhea studies. All patients in post-oral surgery pain studies received single dose of study medication. Doses up to 600 mg/day of celecoxib were studied in primary dysmenorrhea and post-orthopedic surgery pain studies. The types of adverse events in the analgesia and dysmenorrhea studies were similar to those reported in arthritis studies. The only additional adverse event reported was post-dental extraction alveolar osteitis (dry socket) in the post-oral surgery pain studies.The APC and PreSAP TrialsAdverse reactions from long-term, placebo-controlled polyp prevention studies: Exposure to celecoxib in the APC and PreSAP trials was 400 mg to 800 mg daily for up to years [see Clinical Studies (14.7) ].Some adverse reactions occurred in higher percentages of patients than in the arthritis pre-marketing trials (treatment durations up to 12 weeks; see Adverse events from celecoxib pre-marketing controlled arthritis trials, above).

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. See Table for clinically significant drug interactions with celecoxib.Table 3: Clinically Significant Drug Interactions with Celecoxib Drugs That Interfere with Hemostasis Clinical Impact: Celecoxib and anticoagulants such as warfarin have synergistic effect on bleeding. The concomitant use of celecoxib and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone. Serotonin release by platelets plays an important role in hemostasis. Case-control and cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone. Intervention: Monitor patients with concomitant use of celecoxib with anticoagulants (e.g., warfarin), antiplatelet drugs (e.g., aspirin), SSRIs, and SNRIs for signs of bleeding [see Warnings and Precautions (5.12) ]. Aspirin Clinical Impact: Controlled clinical studies showed that the concomitant use of NSAIDs and analgesic doses of aspirin does not produce any greater therapeutic effect than the use of NSAIDs alone. In clinical study, the concomitant use of an NSAID and aspirin was associated with significantly increased incidence of GI adverse reactions as compared to use of the NSAID alone [see Warnings and Precautions (5.2 ].In two studies in healthy volunteers, and in patients with osteoarthritis and established heart disease respectively, celecoxib (200 mg to 400 mg daily) has demonstrated lack of interference with the cardioprotective antiplatelet effect of aspirin (100 mg to 325 mg). Intervention: Concomitant use of celecoxib and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding [see Warnings and Precautions (5.12) ]. Celecoxib is not substitute for low dose aspirin for cardiovascular protection. ACE Inhibitors, Angiotensin Receptor Blockers, and Beta-Blockers Clinical Impact: NSAIDs may diminish the antihypertensive effect of ACE inhibitors, ARBs, or beta-blockers (including propranolol). In patients who are elderly, volume-depleted (including those on diuretic therapy), or have renal impairment, co-administration of an NSAID with ACE inhibitors or ARBs may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Intervention: During concomitant use of celecoxib and ACE inhibitors, ARBs, or beta-blockers, monitor blood pressure to ensure that the desired blood pressure is obtained. During concomitant use of celecoxib and ACE inhibitors or ARBs in patients who are elderly, volume-depleted, or have impaired renal function, monitor for signs of worsening renal function [see Warnings and Precautions (5.6) ]. When these drugs are administered concomitantly, patients should be adequately hydrated. Assess renal function at the beginning of the concomitant treatment and periodically thereafter. Diuretics Clinical Impact: Clinical studies, as well as post-marketing observations, showed that NSAIDs reduced the natriuretic effect of loop diuretics (e.g., furosemide) and thiazide diuretics in some patients. This effect has been attributed to the NSAID inhibition of renal prostaglandin synthesis. Intervention: During concomitant use of celecoxib with diuretics, observe patients for signs of worsening renal function, in addition to assuring diuretic efficacy including antihypertensive effects [see Warnings and Precautions (5.6) ]. Digoxin Clinical Impact: The concomitant use of celecoxib with digoxin has been reported to increase the serum concentration and prolong the half-life of digoxin. Intervention: During concomitant use of celecoxib and digoxin, monitor serum digoxin levels. Lithium Clinical Impact: NSAIDs have produced elevations in plasma lithium levels and reductions in renal lithium clearance. The mean minimum lithium concentration increased 15%, and the renal clearance decreased by approximately 20%. This effect has been attributed to NSAID inhibition of renal prostaglandin synthesis. Intervention: During concomitant use of celecoxib and lithium, monitor patients for signs of lithium toxicity. Methotrexate Clinical Impact: Concomitant use of NSAIDs and methotrexate may increase the risk for methotrexate toxicity (e.g., neutropenia, thrombocytopenia, renal dysfunction).Celecoxib has no effect on methotrexate pharmacokinetics. Intervention: During concomitant use of celecoxib and methotrexate, monitor patients for methotrexate toxicity. Cyclosporine Clinical Impact: Concomitant use of celecoxib and cyclosporine may increase cyclosporines nephrotoxicity. Intervention: During concomitant use of celecoxib and cyclosporine, monitor patients for signs of worsening renal function. NSAIDs and Salicylates Clinical Impact: Concomitant use of celecoxib with other NSAIDs or salicylates (e.g., diflunisal, salsalate) increases the risk of GI toxicity, with little or no increase in efficacy [see Warnings and Precautions (5.2) ]. Intervention: The concomitant use of celecoxib with other NSAIDs or salicylates is not recommended. Pemetrexed Clinical Impact: Concomitant use of celecoxib and pemetrexed may increase the risk of pemetrexed-associated myelosuppression, renal, and GI toxicity (see the pemetrexed prescribing information). Intervention: During concomitant use of celecoxib and pemetrexed, in patients with renal impairment whose creatinine clearance ranges from 45 to 79 mL/min, monitor for myelosuppression, renal and GI toxicity.NSAIDs with short elimination half-lives (e.g., diclofenac, indomethacin) should be avoided for period of two days before, the day of, and two days following administration of pemetrexed.In the absence of data regarding potential interaction between pemetrexed and NSAIDs with longer half-lives (e.g., meloxicam, nabumetone), patients taking these NSAIDs should interrupt dosing for at least five days before, the day of, and two days following pemetrexed administration. CYP2C9 Inhibitors or inducers Clinical Impact: Celecoxib metabolism is predominantly mediated via cytochrome P450 (CYP) 2C9 in the liver. Co-administration of celecoxib with drugs that are known to inhibit CYP2C9 (e.g., fluconazole) may enhance the exposure and toxicity of celecoxib whereas co-administration with CYP2C9 inducers (e.g., rifampin) may lead to compromised efficacy of celecoxib. Intervention Evaluate each patients medical history when consideration is given to prescribing celecoxib. dosage adjustment may be warranted when celecoxib is administered with CYP2C9 inhibitors or inducers [see Clinical Pharmacology (12.3)]. CYP2D6 substrates Clinical Impact: In vitro studies indicate that celecoxib, although not substrate, is an inhibitor of CYP2D6. Therefore, there is potential for an in vivo drug interaction with drugs that are metabolized by CYP2D6 (e.g., atomoxetine), and celecoxib may enhance the exposure and toxicity of these drugs. Intervention Evaluate each patients medical history when consideration is given to prescribing celecoxib. dosage adjustment may be warranted when celecoxib is administered with CYP2D6 substrates [see Clinical Pharmacology (12.3) ]. Corticosteroids Clinical Impact: Concomitant use of corticosteroids with celecoxib may increase the risk of GI ulceration or bleeding. Intervention Monitor patients with concomitant use of celecoxib with corticosteroids for signs of bleeding [see Warnings and Precautions (5.2)].. Celecoxib and anticoagulants such as warfarin have synergistic effect on bleeding. The concomitant use of celecoxib and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone. Serotonin release by platelets plays an important role in hemostasis. Case-control and cohort epidemiological studies showed that concomitant use of drugs that interfere with serotonin reuptake and an NSAID may potentiate the risk of bleeding more than an NSAID alone.. NSAIDs may diminish the antihypertensive effect of ACE inhibitors, ARBs, or beta-blockers (including propranolol). In patients who are elderly, volume-depleted (including those on diuretic therapy), or have renal impairment, co-administration of an NSAID with ACE inhibitors or ARBs may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible.. During concomitant use of celecoxib and ACE inhibitors, ARBs, or beta-blockers, monitor blood pressure to ensure that the desired blood pressure is obtained. During concomitant use of celecoxib and ACE inhibitors or ARBs in patients who are elderly, volume-depleted, or have impaired renal function, monitor for signs of worsening renal function [see Warnings and Precautions (5.6) ]. When these drugs are administered concomitantly, patients should be adequately hydrated. Assess renal function at the beginning of the concomitant treatment and periodically thereafter.. Drugs that Interfere with Hemostasis (e.g., warfarin, aspirin, selective serotonin reuptake inhibitors [SSRIs]/serotonin norepinephrine reuptake inhibitors [SNRIs]): Monitor patients for bleeding who are concomitantly taking celecoxib with drugs that interfere with hemostasis. Concomitant use of celecoxib and analgesic doses of aspirin is not generally recommended. (7) Angiotensin Converting Enzyme (ACE) Inhibitors, Angiotensin Receptor Blockers (ARB), or Beta-Blockers: Concomitant use with celecoxib may diminish the antihypertensive effect of these drugs. Monitor blood pressure. (7)ACE Inhibitors and ARBs: Concomitant use with celecoxib in elderly, volume depleted, or those with renal impairment may result in deterioration of renal function. In such high risk patients, monitor for signs of worsening renal function. (7) Diuretics: NSAIDs can reduce natriuretic effect of furosemide and thiazide diuretics. Monitor patients to assure diuretic efficacy including antihypertensive effects. (7)Digoxin: Concomitant use with celecoxib can increase serum concentration and prolong half-life of digoxin. Monitor serum digoxin levels. (7). Drugs that Interfere with Hemostasis (e.g., warfarin, aspirin, selective serotonin reuptake inhibitors [SSRIs]/serotonin norepinephrine reuptake inhibitors [SNRIs]): Monitor patients for bleeding who are concomitantly taking celecoxib with drugs that interfere with hemostasis. Concomitant use of celecoxib and analgesic doses of aspirin is not generally recommended. (7) Angiotensin Converting Enzyme (ACE) Inhibitors, Angiotensin Receptor Blockers (ARB), or Beta-Blockers: Concomitant use with celecoxib may diminish the antihypertensive effect of these drugs.

Monitor serum digoxin levels. (7).

FEMALES & MALES OF REPRODUCTIVE POTENTIAL SECTION.

8.3 Females and Males of Reproductive Potential. InfertilityFemalesBased on the mechanism of action, the use of prostaglandin-mediated NSAIDs, including celecoxib, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women. Published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandin mediated follicular rupture required for ovulation. Small studies in women treated with NSAIDs have also shown reversible delay in ovulation. Consider withdrawal of NSAIDs, including celecoxib, in women who have difficulties conceiving or who are undergoing investigation of infertility.

GERIATRIC USE SECTION.

8.5 Geriatric Use. Elderly patients, compared to younger patients, are at greater risk for NSAID-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions. If the anticipated benefit for the elderly patient outweighs these potential risks, start dosing at the low end of the dosing range, and monitor patients for adverse effects [see Warnings and Precautions 5.1 5.2 5.3 5.6 5.14 )].Of the total number of patients who received celecoxib in pre-approval clinical trials, more than 3,300 were 65-74 years of age, while approximately 1,300 additional patients were 75 years and over. No substantial differences in effectiveness were observed between these subjects and younger subjects. In clinical studies comparing renal function as measured by the GFR, BUN and creatinine, and platelet function as measured by bleeding time and platelet aggregation, the results were not different between elderly and young volunteers. However, as with other NSAIDs, including those that selectively inhibit COX-2, there have been more spontaneous post-marketing reports of fatal GI events and acute renal failure in the elderly than in younger patients [see Warnings and Precautions 5.2 5.6 )].

INFORMATION FOR PATIENTS SECTION.

17 PATIENT COUNSELING INFORMATION. Advise the patient to read the FDA-approved patient labeling (Medication Guide) that accompanies each prescription dispensed. Inform patients, families, or their caregivers of the following information before initiating therapy with celecoxib and periodically during the course of ongoing therapy.Cardiovascular Thrombotic EventsAdvise patients to be alert for the symptoms of cardiovascular thrombotic events, including chest pain, shortness of breath, weakness, or slurring of speech, and to report any of these symptoms to their health care provider immediately [see Warnings and Precautions (5.1) ].Gastrointestinal Bleeding, Ulceration, and PerforationAdvise patients to report symptoms of ulcerations and bleeding, including epigastric pain, dyspepsia, melena, and hematemesis to their health care provider. In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, inform patients of the increased risk for and the signs and symptoms of GI bleeding [see Warnings and Precautions (5.2) ].HepatotoxicityInform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, pruritus, diarrhea jaundice, right upper quadrant tenderness, and flu-like symptoms). If these occur, instruct patients to stop celecoxib capsules and seek immediate medical therapy [see Warnings and Precautions (5.3) Use in Specific Populations (8.6) ].Heart Failure and EdemaAdvise patients to be alert for the symptoms of congestive heart failure including shortness of breath, unexplained weight gain, or edema and to contact their healthcare provider if such symptoms occur [see Warnings and Precautions (5.5) ].Anaphylactic ReactionsInform patients of the signs of an anaphylactic reaction (e.g., difficulty breathing, swelling of the face or throat). Instruct patients to seek immediate emergency help if these occur [see Contraindications (4) and Warnings and Precautions (5.7) ].Serious Skin Reactions, including DRESSAdvise patients to stop taking celecoxib capsules immediately if they develop any type of rash or fever and to contact their healthcare provider as soon as possible [see Warnings and Precautions (5.9, 5.10)].Female FertilityAdvise females of reproductive potential who desire pregnancy that NSAIDs, including celecoxib, may be associated with reversible delay in ovulation [see Use in Specific Populations (8.3)].Fetal ToxicityInform pregnant women to avoid use of celecoxib and other NSAIDs starting at 30 weeks of gestation because of the risk of the premature closing of the fetal ductus arteriosus. If treatment with celecoxib is needed for pregnant woman between about 20 to 30 weeks gestation, advise her that she may need to be monitored for oligohydramnios, if treatment continues for longer than 48 hours [see Warnings and Precautions (5.11) and Use in Specific Populations (8.1)].Avoid Concomitant Use of NSAIDsInform patients that the concomitant use of celecoxib with other NSAIDs or salicylates (e.g., diflunisal, salsalate) is not recommended due to the increased risk of gastrointestinal toxicity, and little or no increase in efficacy [see Warnings and Precautions (5.2) and Drug Interactions (7) ]. Alert patients that NSAIDs may be present in over the counter medications for treatment of colds, fever, or insomnia.Use of NSAIDS and Low-Dose AspirinInform patients not to use low-dose aspirin concomitantly with celecoxib capsules until they talk to their healthcare provider [see Drug Interactions (7) ].Manufactured in India by: Watson Pharma Private Limited Verna, Salcette Goa 403 722 INDIADistributed by: Actavis Pharma, Inc.

LACTATION SECTION.

8.2 Lactation. Risk SummaryLimited data from published reports that included total of 12 breastfeeding women showed low levels of celecoxib in breast milk. The calculated average daily infant dose was 10 to 40 mcg/kg/day, less than 1% of the weight-based therapeutic dose for two-year old-child. report of two breastfed infants 17 and 22 months of age did not show any adverse events. Caution should be exercised when celecoxib is administered to nursing woman. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for celecoxib and any potential adverse effects on the breastfed infant from the celecoxib or from the underlying maternal condition.

MECHANISM OF ACTION SECTION.

12.1 Mechanism of Action. Celecoxib has analgesic, anti-inflammatory, and antipyretic properties.The mechanism of action of celecoxib is believed to be due to inhibition of prostaglandin synthesis, primarily via inhibition of COX-2.Celecoxib is potent inhibitor of prostaglandin synthesis in vitro. Celecoxib concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Since celecoxib is an inhibitor of prostaglandin synthesis, its mode of action may be due to decrease of prostaglandins in peripheral tissues.

USE IN SPECIFIC POPULATIONS SECTION.

2.7 Special Populations. Hepatic ImpairmentIn patients with moderate hepatic impairment (Child-Pugh Class B), reduce the dose by 50%. The use of celecoxib in patients with severe hepatic impairment is not recommended [see Warnings and Precautions (5.3) Use in Specific Populations (8.6), and Clinical Pharmacology (12.3) ].Poor Metabolizers of CYP2C9 SubstratesIn adult patients who are known or suspected to be poor CYP2C9 metabolizers based on genotype or previous history/experience with other CYP2C9 substrates (such as warfarin, phenytoin), initiate treatment with half of the lowest recommended dose.In patients with JRA who are known or suspected to be poor CYP2C9 metabolizers, consider using alternative treatments [see Use in Specific populations (8.8) and Clinical Pharmacology (12.5) ].

(5.11, 8.1). Hematologic Toxicity: Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia. (5.12, 7). 5.1 Cardiovascular Thrombotic Events. Clinical trials of several cyclooxygenase-2 (COX-2) selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, including myocardial infarction (MI) and stroke, which can be fatal. Based on available data, it is unclear that the risk for CV thrombotic events is similar for all NSAIDs. The relative increase in serious CV thrombotic events over baseline conferred by NSAID use appears to be similar in those with and without known CV disease or risk factors for CV disease. However, patients with known CV disease or risk factors had higher absolute incidence of excess serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of serious CV thrombotic events began as early as the first weeks of treatment. The increase in CV thrombotic risk has been observed most consistently at higher doses.In the APC (Adenoma Prevention with Celecoxib) trial, there was about threefold increased risk of the composite endpoint of cardiovascular death, MI, or stroke for the celecoxib 400 mg twice daily and celecoxib 200 mg twice daily treatment arms compared to placebo. The increases in both celecoxib dose groups versus placebo-treated patients were mainly due to an increased incidence of myocardial infarction [see Clinical Studies (14.7)].A randomized controlled trial entextd the Prospective Randomized Evaluation of Celecoxib Integrated Safety vs. Ibuprofen Or Naproxen (PRECISION) was conducted to assess the relative cardiovascular thrombotic risk of COX-2 inhibitor, celecoxib, compared to the non-selective NSAIDs naproxen and ibuprofen. Celecoxib 100 mg twice daily was non-inferior to naproxen 375 to 500 mg twice daily and ibuprofen 600 to 800 mg three times daily for the composite endpoint of the Antiplatelet Trialists Collaboration (APTC), which consists of cardiovascular death (including hemorrhagic death), non-fatal myocardial infarction, and non-fatal stroke [see Clinical Studies (14.6)].To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest duration possible. Physicians and patients should remain alert for the development of such events, throughout the entire treatment course, even in the absence of previous CV symptoms. Patients should be informed about the symptoms of serious CV events and the steps to take if they occur.There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID, such as celecoxib, increases the risk of serious gastrointestinal (GI) events [see Warnings and Precautions (5.2) ].Status Post Coronary Artery Bypass Graft (CABG) SurgeryTwo large, controlled clinical trials of COX-2 selective NSAID for the treatment of pain in the first 10 to 14 days following CABG surgery found an increased incidence of myocardial infarction and stroke. NSAIDs are contraindicated in the setting of CABG [see Contraindications (4) ].Post-MI PatientsObservational studies conducted in the Danish National Registry have demonstrated that patients treated with NSAIDs in the post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of treatment. In this same cohort, the incidence of death in the first year post-MI was 20 per 100 person years in NSAID-treated patients compared to 12 per 100 person years in non-NSAID exposed patients. Although the absolute rate of death declined somewhat after the first year post-MI, the increased relative risk of death in NSAID users persisted over at least the next four years of follow-up.Avoid the use of celecoxib in patients with recent MI unless the benefits are expected to outweigh the risk of recurrent CV thrombotic events. If celecoxib is used in patients with recent MI, monitor patients for signs of cardiac ischemia.. 5.2 Gastrointestinal Bleeding, Ulceration, and Perforation. NSAIDs, including celecoxib cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with celecoxib. Only one in five patients who develop serious upper GI adverse event on NSAID therapy is symptomatic. Upper GI ulcers, gross bleeding, or perforation caused by NSAIDs occurred in approximately 1% of patients treated for to months, and in about 2% to 4% of patients treated for one year. However, even short-term NSAID therapy is not without risk.Risk Factors for GI Bleeding, Ulceration, and PerforationPatients with prior history of peptic ulcer disease and/or GI bleeding who used NSAIDs had greater than 10-fold increased risk for developing GI bleed compared to patients without these risk factors. Other factors that increase the risk of GI bleeding in patients treated with NSAIDs include longer duration of NSAID therapy; concomitant use of oral corticosteroids, antiplatelet drugs (such as aspirin), anticoagulants; or selective serotonin reuptake inhibitors (SSRIs); smoking; use of alcohol; older age; and poor general health status. Most postmarketing reports of fatal GI events occurred in elderly or debilitated patients. Additionally, patients with advanced liver disease and/or coagulopathy are at increased risk for GI bleeding.Complicated and symptomatic ulcer rates were 0.78% at nine months for all patients in the CLASS trial, and 2.19% for the subgroup on low-dose ASA. Patients 65 years of age and older had an incidence of 1.40% at nine months, 3.06% when also taking ASA [see Clinical Studies (14.7) ].Strategies to Minimize the GI Risks in NSAID-treated patients:Use the lowest effective dosage for the shortest possible duration. Avoid administration of more than one NSAID at time. Avoid use in patients at higher risk unless benefits are expected to outweigh the increased risk of bleeding. For such patients, as well as those with active GI bleeding, consider alternate therapies other than NSAIDs. Remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy. If serious GI adverse event is suspected, promptly initiate evaluation and treatment, and discontinue celecoxib until serious GI adverse event is ruled out. In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, monitor patients more closely for evidence of GI bleeding [see Drug Interactions (7) ].. Use the lowest effective dosage for the shortest possible duration. Avoid administration of more than one NSAID at time. Avoid use in patients at higher risk unless benefits are expected to outweigh the increased risk of bleeding. For such patients, as well as those with active GI bleeding, consider alternate therapies other than NSAIDs. Remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy. If serious GI adverse event is suspected, promptly initiate evaluation and treatment, and discontinue celecoxib until serious GI adverse event is ruled out. In the setting of concomitant use of low-dose aspirin for cardiac prophylaxis, monitor patients more closely for evidence of GI bleeding [see Drug Interactions (7) ].. 5.3 Hepatotoxicity. Elevations of ALT or AST (three or more times the upper limit of normal [ULN]) have been reported in approximately 1% of NSAID-treated patients in clinical trials. In addition, rare, sometimes fatal, cases of severe hepatic injury, including fulminant hepatitis, liver necrosis, and hepatic failure have been reported.Elevations of ALT or AST (less than three times ULN) may occur in up to 15% of patients treated with NSAIDs including celecoxib.In controlled clinical trials of celecoxib, the incidence of borderline elevations (greater than or equal to 1.2 times and less than times the upper limit of normal) of liver associated enzymes was 6% for celecoxib and 5% for placebo, and approximately 0.2% of patients taking celecoxib and 0.3% of patients taking placebo had notable elevations of ALT and AST.Inform patients of the warning signs and symptoms of hepatotoxicity (e.g., nausea, fatigue, lethargy, diarrhea, pruritus, jaundice, right upper quadrant tenderness, and flu-like symptoms). If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur (e.g., eosinophilia, rash), discontinue celecoxib capsules immediately, and perform clinical evaluation of the patient.. 5.4 Hypertension. NSAIDs, including celecoxib, can lead to new onset of hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of CV events. Patients taking angiotensin converting enzyme (ACE) inhibitors, thiazide diuretics or loop diuretics may have impaired response to these therapies when taking NSAIDs [see Drug Interactions (7) ].See Clinical Studies (14. 6, 14.7) for additional blood pressure data for celecoxib.Monitor blood pressure (BP) during the initiation of NSAID treatment and throughout the course of therapy.. 5.5 Heart Failure and Edema. The Coxib and traditional NSAID Trialists Collaboration meta-analysis of randomized controlled trials demonstrated an approximately two-fold increase in hospitalizations for heart failure in COX-2 selective-treated patients and nonselective NSAID-treated patients compared to placebo-treated patients. In Danish National Registry study of patients with heart failure, NSAID use increased the risk of MI, hospitalization for heart failure, and death.Additionally, fluid retention and edema have been observed in some patients treated with NSAIDs. Use of celecoxib may blunt the CV effects of several therapeutic agents used to treat these medical conditions (e.g., diuretics, ACE inhibitors, or angiotensin receptor blockers [ARBs]) [see Drug Interactions (7) ].In the CLASS study [see Clinical Studies (14.7) ], the Kaplan-Meier cumulative rates at months of peripheral edema in patients on celecoxib capsules 400 mg twice daily (4-fold and 2-fold the recommended OA and RA doses, respectively), ibuprofen 800 mg three times daily and diclofenac 75 mg twice daily were 4.5%, 6.9% and 4.7%, respectively.Avoid the use of celecoxib capsules in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure. If celecoxib capsules are used in patients with severe heart failure, monitor patients for signs of worsening heart failure.. 5.6 Renal Toxicity and Hyperkalemia. Renal ToxicityLong-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury.Renal toxicity has also been seen in patients in whom renal prostaglandins have compensatory role in the maintenance of renal perfusion. In these patients, administration of an NSAID may cause dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, dehydration, hypovolemia, heart failure, liver dysfunction, those taking diuretics, ACE inhibitors or the ARBs, and the elderly. Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state.No information is available from controlled clinical studies regarding the use of celecoxib in patients with advanced renal disease. The renal effects of celecoxib may hasten the progression of renal dysfunction in patients with preexisting renal disease.Correct volume status in dehydrated or hypovolemic patients prior to initiating celecoxib. Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia during use of celecoxib [see Drug Interactions (7) ]. Avoid the use of celecoxib in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal function. If celecoxib capsules are used in patients with advanced renal disease, monitor patients for signs of worsening renal function.HyperkalemiaIncreases in serum potassium concentration, including hyperkalemia, have been reported with use of NSAIDs, even in some patients without renal impairment. In patients with normal renal function, these effects have been attributed to hyporeninemic- hypoaldosteronism state.. 5.7 Anaphylactic Reactions. Celecoxib has been associated with anaphylactic reactions in patients with and without known hypersensitivity to celecoxib and in patients with aspirin sensitive asthma. Celecoxib is sulfonamide and both NSAIDs and sulfonamides may cause allergic type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people [see Contraindications (4) and Warnings and Precautions (5.8) ].Seek emergency help if any anaphylactic reaction occurs.. 5.8 Exacerbation of Asthma Related to Aspirin Sensitivity. subpopulation of patients with asthma may have aspirin-sensitive asthma which may include chronic rhinosinusitis complicated by nasal polyps; severe, potentially fatal bronchospasm; and/or intolerance to aspirin and other NSAIDs. Because cross-reactivity between aspirin and other NSAIDs has been reported in such aspirin-sensitive patients, celecoxib is contraindicated in patients with this form of aspirin sensitivity [see Contraindications (4) ]. When celecoxib capsules are used in patients with preexisting asthma (without known aspirin sensitivity), monitor patients for changes in the signs and symptoms of asthma.. 5.9 Serious Skin Reactions. Serious skin reactions have occurred following treatment with celecoxib, including erythema multiforme, exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP). These serious events may occur without warning and can be fatal.Inform patients about the signs and symptoms of serious skin reactions, and to discontinue the use of celecoxib capsules at the first appearance of skin rash or any other sign of hypersensitivity. Celecoxib is contraindicated in patients with previous serious skin reactions to NSAIDs [see Contraindications (4) ].. 5.10 Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported in patients taking NSAIDs such as celecoxib. Some of these events have been fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling. Other clinical manifestations may include hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis. Sometimes symptoms of DRESS may resemble an acute viral infection. Eosinophilia is often present. Because this disorder is variable in its presentation, other organ systems not noted here may be involved. It is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident. If such signs or symptoms are present, discontinue celecoxib and evaluate the patient immediately.. 5.11 Fetal Toxicity. Premature Closure of Fetal Ductus ArteriosusAvoid use of NSAIDs, including celecoxib, in pregnant women at about 30 weeks gestation and later. NSAIDs, including celecoxib, increase the risk of premature closure of the fetal ductus arteriosus at approximately this gestational age.Oligohydramnios/Neonatal Renal ImpairmentUse of NSAIDs, including celecoxib, at about 20 weeks gestation or later in pregnancy may cause fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation. Oligohydramnios is often, but not always, reversible with treatment discontinuation. Complications of prolonged oligohydramnios may, for example, include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures such as exchange transfusion or dialysis were required.If NSAID treatment is necessary between about 20 weeks and 30 weeks gestation, limit celecoxib use to the lowest effective dose and shortest duration possible. Consider ultrasound monitoring of amniotic fluid if celecoxib treatment extends beyond 48 hours. Discontinue celecoxib if oligohydramnios occurs and follow up according to clinical practice [see Use in Specific Populations (8.1)]. 5.12 Hematological Toxicity. Anemia has occurred in NSAID-treated patients. This may be due to occult or gross blood loss, fluid retention, or an incompletely described effect on erythropoiesis. If patient treated with celecoxib has any signs or symptoms of anemia, monitor hemoglobin or hematocrit.In controlled clinical trials the incidence of anemia was 0.6% with celecoxib and 0.4% with placebo. Patients on long-term treatment with celecoxib should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia or blood loss.NSAIDs, including celecoxib, may increase the risk of bleeding events. Co-morbid conditions such as coagulation disorders or concomitant use of warfarin, other anticoagulants, antiplatelet drugs (e.g., aspirin), SSRIs and serotonin norepinephrine reuptake inhibitors (SNRIs) may increase this risk. Monitor these patients for signs of bleeding [see Drug Interactions (7) ].. 5.13 Masking of Inflammation and Fever. The pharmacological activity of celecoxib in reducing inflammation, and possibly fever, may diminish the utility of diagnostic signs in detecting infections.. 5.14 Laboratory Monitoring. Because serious GI bleeding, hepatotoxicity, and renal injury can occur without warning symptoms or signs, consider monitoring patients on long-term NSAID treatment with CBC and chemistry profile periodically [see Warnings and Precautions 5.2 5.3 5.6 )].In controlled clinical trials, elevated BUN occurred more frequently in patients receiving celecoxib compared with patients on placebo. This laboratory abnormality was also seen in patients who received comparator NSAIDs in these studies. The clinical significance of this abnormality has not been established.. 5.15 Disseminated Intravascular Coagulation (DIC). Because of the risk of disseminated intravascular coagulation with use of celecoxib in pediatric patients with systemic onset JRA, monitor patients for signs and symptoms of abnormal clotting or bleeding, and inform patients and their caregivers to report symptoms as soon as possible.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. CarcinogenesisCelecoxib was not carcinogenic in Sprague-Dawley rats given oral doses up to 200 mg/kg for males and 10 mg/kg for females (approximately 2- to 4-times the human exposure as measured by the AUC0-24 at 200 mg twice daily) or in mice given oral doses up to 25 mg/kg for males and 50 mg/kg for females (approximately equal to human exposure as measured by the AUC0-24 at 200 mg twice daily) for two years.MutagenesisCelecoxib was not mutagenic in an Ames test and mutation assay in Chinese hamster ovary (CHO) cells, nor clastogenic in chromosome aberration assay in CHO cells and an in vivo micronucleus test in rat bone marrow.Impairment of FertilityCelecoxib had no effect on male or female fertility or male reproductive function in rats at oral doses up to 600 mg/kg/day (approximately 11-times human exposure at 200 mg twice daily based on the AUC0-24). At >=50 mg/kg/day (approximately 6-times human exposure based on the AUC0-24 at 200 mg twice daily) there was increased preimplantation loss.. 13.2 Animal Toxicology. An increase in the incidence of background findings of spermatocele with or without secondary changes such as epididymal hypospermia as well as minimal to slight dilation of the seminiferous tubules was seen in the juvenile rat. These reproductive findings while apparently treatment-related did not increase in incidence or severity with dose and may indicate an exacerbation of spontaneous condition. Similar reproductive findings were not observed in studies of juvenile or adult dogs or in adult rats treated with celecoxib. The clinical significance of this observation is unknown.

OVERDOSAGE SECTION.

10 OVERDOSAGE. Symptoms following acute NSAID overdosages have been typically limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which have been generally reversible with supportive care. Gastrointestinal bleeding has occurred. Hypertension, acute renal failure, respiratory depression, and coma have occurred, but were rare [see Warnings and Precautions 5.2 5.4 5.6 )].No overdoses of celecoxib were reported during clinical trials. Doses up to 2400 mg/day for up to 10 days in 12 patients did not result in serious toxicity. No information is available regarding the removal of celecoxib by hemodialysis, but based on its high degree of plasma protein binding (97%) dialysis is unlikely to be useful in overdose.Manage patients with symptomatic and supportive care following an NSAID overdosage. There are no specific antidotes. Consider emesis and/or activated charcoal (60 to 100 grams in adults, to grams per kg of body weight in pediatric patients) and/or osmotic cathartic in symptomatic patients seen within four hours of ingestion or in patients with large overdosage (5 to 10 times the recommended dosage). Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding.For additional information about overdosage treatment contact poison control center (1-800-222-1222).

PEDIATRIC USE SECTION.

8.4 Pediatric Use. Celecoxib is approved for relief of the signs and symptoms of Juvenile Rheumatoid Arthritis in patients years and older. Safety and efficacy have not been studied beyond six months in children. The long-term cardiovascular toxicity in children exposed to celecoxib has not been evaluated and it is unknown if long-term risks may be similar to that seen in adults exposed to celecoxib or other COX-2 selective and non-selective NSAIDs [see Boxed Warning Warnings and Precautions (5.5) and Clinical Studies (14.3) ].The use of celecoxib in patients years to 17 years of age with pauciarticular, polyarticular course JRA or in patients with systemic onset JRA was studied in 12-week, double-blind, active controlled, pharmacokinetic, safety and efficacy study, with 12-week open-label extension. Celecoxib has not been studied in patients under the age of years, in patients with body weight less than 10 kg (22 lbs), and in patients with active systemic features. Patients with systemic onset JRA (without active systemic features) appear to be at risk for the development of abnormal coagulation laboratory tests. In some patients with systemic onset JRA, both celecoxib and naproxen were associated with mild prolongation of activated partial thromboplastin time (APTT) but not prothrombin time (PT). When NSAIDs including celecoxib are used in patients with systemic onset JRA, monitor patients for signs and symptoms of abnormal clotting or bleeding, due to the risk of disseminated intravascular coagulation. Patients with systemic onset JRA should be monitored for the development of abnormal coagulation tests [see Dosage and Administration (2.4) Warnings and Precautions (5.15) Adverse Reactions (6.1), Animal Toxicology (13.2) Clinical Studies (14.3) ].Alternative therapies for treatment of JRA should be considered in pediatric patients identified to be CYP2C9 poor metabolizers [see Poor Metabolizers of CYP2C9 substrates (8.8) ].

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. PlateletsIn clinical trials using normal volunteers, celecoxib at single doses up to 800 mg and multiple doses of 600 mg twice daily for up to days duration (higher than recommended therapeutic doses) had no effect on reduction of platelet aggregation or increase in bleeding time. Because of its lack of platelet effects, celecoxib is not substitute for aspirin for cardiovascular prophylaxis. It is not known if there are any effects of celecoxib on platelets that may contribute to the increased risk of serious cardiovascular thrombotic adverse events associated with the use of celecoxib.Fluid RetentionInhibition of PGE2 synthesis may lead to sodium and water retention through increased reabsorption in the renal medullary thick ascending loop of Henle and perhaps other segments of the distal nephron. In the collecting ducts, PGE2 appears to inhibit water reabsorption by counteracting the action of antidiuretic hormone.

PHARMACOGENOMICS SECTION.

12.5 Pharmacogenomics. CYP2C9 activity is reduced in individuals with genetic polymorphisms that lead to reduced enzyme activity, such as those homozygous for the CYP2C92 and CYP2C93 polymorphisms. Limited data from published reports that included total of subjects with the homozygous CYP2C93/3 genotype showed celecoxib systemic levels that were 3- to 7-fold higher in these subjects compared to subjects with CYP2C91/1 or I/3 genotypes. The pharmacokinetics of celecoxib have not been evaluated in subjects with other CYP2C9 polymorphisms, such as 2, 5, 6, and 11. It is estimated that the frequency of the homozygous 3/3 genotype is 0.3% to 1.0% in various ethnic groups [see Dosage and Administration (2.7) Use in Specific Populations (8.8) ].

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. Celecoxib exhibits dose-proportional increase in exposure after oral administration up to 200 mg twice daily and less than proportional increase at higher doses. It has extensive distribution and high protein binding. It is primarily metabolized by CYP2C9 with half-life of approximately 11 hours.AbsorptionPeak plasma levels of celecoxib occur approximately hours after an oral dose. Under fasting conditions, both peak plasma levels (Cmax) and area under the curve (AUC) are roughly dose-proportional up to 200 mg twice daily; at higher doses there are less than proportional increases in Cmax and AUC (see Food Effects). Absolute bioavailability studies have not been conducted. With multiple dosing, steady-state conditions are reached on or before Day 5. The pharmacokinetic parameters of celecoxib in group of healthy subjects are shown in Table 4.Table 4: Summary of Single Dose (200 mg) Disposition Kinetics of Celecoxib in Healthy Subjects1 Mean (%CV) PK Parameter Values max ng/mL max hr Effective 1/2 hr ss /F, CL/F, L/hr 705 (38) 2.8 (37) 11.2 (31) 429 (34) 27.7 (28) Subjects under fasting conditions (n=36, 19-52 yrs.)Food EffectsWhen celecoxib capsules were taken with high fat meal, peak plasma levels were delayed for about to hours with an increase in total absorption (AUC) of 10% to 20%. Under fasting conditions, at doses above 200 mg, there is less than proportional increase in Cmax and AUC, which is thought to be due to the low solubility of the drug in aqueous media.Coadministration of celecoxib capsules with an aluminum- and magnesium-containing antacids resulted in reduction in plasma celecoxib concentrations with decrease of 37% in Cmax and 10% in AUC. Celecoxib capsules, at doses up to 200 mg twice daily, can be administered without regard to timing of meals. Higher doses (400 mg twice daily) should be administered with food to improve absorption.In healthy adult volunteers, the overall systemic exposure (AUC) of celecoxib was equivalent when celecoxib was administered as intact capsule or capsule contents sprinkled on applesauce. There were no significant alterations in Cmax, Tmax or t1/2 after administration of capsule contents on applesauce [see Dosage and Administration (2) ].DistributionIn healthy subjects, celecoxib is highly protein bound (~97%) within the clinical dose range. In vitro studies indicate that celecoxib binds primarily to albumin and, to lesser extent, 1-acid glycoprotein. The apparent volume of distribution at steady state (Vss/F) is approximately 400 L, suggesting extensive distribution into the tissues. Celecoxib is not preferentially bound to red blood cells.EliminationMetabolismCelecoxib metabolism is primarily mediated via CYP2C9. Three metabolites, primary alcohol, the corresponding carboxylic acid and its glucuronide conjugate, have been identified in human plasma. These metabolites are inactive as COX-1 or COX-2 inhibitors.ExcretionCelecoxib is eliminated predominantly by hepatic metabolism with little (<3%) unchanged drug recovered in the urine and feces. Following single oral dose of radiolabeled drug, approximately 57% of the dose was excreted in the feces and 27% was excreted into the urine. The primary metabolite in both urine and feces was the carboxylic acid metabolite (73% of dose) with low amounts of the glucuronide also appearing in the urine. It appears that the low solubility of the drug prolongs the absorption process making terminal half-life (t1/2) determinations more variable. The effective half-life is approximately 11 hours under fasted conditions. The apparent plasma clearance (CL/F) is about 500 mL/min.Specific PopulationsGeriatricAt steady state, elderly subjects (over 65 years old) had 40% higher Cmax and 50% higher AUC compared to the young subjects. In elderly females, celecoxib Cmax and AUC are higher than those for elderly males, but these increases are predominantly due to lower body weight in elderly females. Dose adjustment in the elderly is not generally necessary. However, for patients of less than 50 kg in body weight, initiate therapy at the lowest recommended dose [see Use in Specific Populations (8.5) ].PediatricThe steady state pharmacokinetics of celecoxib administered as an investigational oral suspension was evaluated in 152 JRA patients years to 17 years of age weighing >=10 kg with pauciarticular or polyarticular course JRA and in patients with systemic onset JRA. Population pharmacokinetic analysis indicated that the oral clearance (unadjusted for body weight) of celecoxib increases less than proportionally to increasing weight, with 10 kg and 25 kg patients predicted to have 40% and 24% lower clearance, respectively, compared with 70 kg adult RA patient.Twice-daily administration of 50 mg capsules to JRA patients weighing >=12 to <=25 kg and 100 mg capsules to JRA patients weighing 25 kg should achieve plasma concentrations similar to those observed in clinical trial that demonstrated the non-inferiority of celecoxib to naproxen 7.5 mg/kg twice daily [see Dosage and Administration (2.4)]. Celecoxib has not been studied in JRA patients under the age of years, in patients with body weight less than 10 kg (22 lbs), or beyond 24 weeks.RaceMeta-analysis of pharmacokinetic studies has suggested an approximately 40% higher AUC of celecoxib in Blacks compared to Caucasians. The cause and clinical significance of this finding is unknown.Hepatic ImpairmentA pharmacokinetic study in subjects with mild (Child-Pugh Class A) and moderate (Child-Pugh Class B) hepatic impairment has shown that steady-state celecoxib AUC is increased about 40% and 180%, respectively, above that seen in healthy control subjects. Therefore, the daily recommended dose of celecoxib capsules should be reduced by approximately 50% in patients with moderate (Child-Pugh Class B) hepatic impairment. Patients with severe hepatic impairment (Child-Pugh Class C) have not been studied. The use of celecoxib in patients with severe hepatic impairment is not recommended [see Dosage and Administration (2.7) and Use in Specific Populations (8.6) ].Renal ImpairmentIn cross-study comparison, celecoxib AUC was approximately 40% lower in patients with chronic renal insufficiency (GFR 35-60 mL/min) than that seen in subjects with normal renal function. No significant relationship was found between GFR and celecoxib clearance. Patients with severe renal insufficiency have not been studied. Similar to other NSAIDs, celecoxib is not recommended in patients with severe renal insufficiency [see Warnings and Precautions (5.6) ].Drug Interaction StudiesIn vitro studies indicate that celecoxib is not an inhibitor of cytochrome P450 2C9, 2C19 or 3A4.In vivo studies have shown the following:AspirinWhen NSAIDs were administered with aspirin, the protein binding of NSAIDs were reduced, although the clearance of free NSAID was not altered. The clinical significance of this interaction is not known. See Table for clinically significant drug interactions of NSAIDs with aspirin [see Drug Interactions (7)].LithiumIn study conducted in healthy subjects, mean steady-state lithium plasma levels increased approximately 17% in subjects receiving lithium 450 mg twice daily with celecoxib capsules 200 mg twice daily as compared to subjects receiving lithium alone [see Drug Interactions (7) ].FluconazoleConcomitant administration of fluconazole at 200 mg once daily resulted in two-fold increase in celecoxib plasma concentration. This increase is due to the inhibition of celecoxib metabolism via P450 2C9 by fluconazole [see Drug Interactions (7) ].Other DrugsThe effects of celecoxib on the pharmacokinetics and/or pharmacodynamics of glyburide, ketoconazole, [see Drug Interactions (7) ], phenytoin, and tolbutamide have been studied in vivo and clinically important interactions have not been found.

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryUse of NSAIDs, including celecoxib, can cause premature closure of the fetal ductus arteriosus and fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. Because of these risks, limit dose and duration of celecoxib use between about 20 and 30 weeks of gestation and avoid celecoxib use at about 30 weeks of gestation and later in pregnancy (see Clinical Considerations, Data). Premature Closure of Fetal Ductus ArteriosusUse of NSAIDs, including celecoxib, at about 30 weeks gestation or later in pregnancy increases the risk of premature closure of the fetal ductus arteriosus.Oligohydramnios/Neonatal Renal ImpairmentUse of NSAIDs at about 20 weeks gestation or later in pregnancy has been associated with cases of fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment.Data from observational studies regarding other potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. In animal reproduction studies, embryo-fetal deaths and an increase in diaphragmatic hernias were observed in rats administered celecoxib daily during the period of organogenesis at oral doses approximately times the maximum recommended human dose (MRHD) of 200 mg twice daily. In addition, structural abnormalities (e.g., septal defects, ribs fused, sternebrae fused and sternebrae misshapen) were observed in rabbits given daily oral doses of celecoxib during the period of organogenesis at approximately times the MRHD (see Data). Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as celecoxib, resulted in increased pre- and post-implantation loss. Prostaglandins also have been shown to have an important role in fetal kidney development. In published animal studies, prostaglandin synthesis inhibitors have been reported to impair kidney development when administered at clinically relevant doses.The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical ConsiderationsFetal/Neonatal Adverse ReactionsPremature closure of Fetal Ductus Arteriosus:Avoid use of NSAIDs in women at about 30 weeks gestation and later in pregnancy, because NSAIDs, including celecoxib, can cause premature closure of the fetal ductus arteriosus (see Data).Oligohydramnios/Neonatal Renal Impairment: If an NSAID is necessary at about 20 weeks gestation or later in pregnancy, limit the use to the lowest effective dose and shortest duration possible. If celecoxib treatment extends beyond 48 hours, consider monitoring with ultrasound for oligohydramnios. If oligohydramnios occurs, discontinue celecoxib and follow up according to clinical practice (see Data).Labor or DeliveryThere are no studies on the effects of celecoxib during labor or delivery. In animal studies, NSAIDs, including celecoxib, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth.DataHuman DataThe available data do not establish the presence or absence of developmental toxicity related to the use of celecoxib.Premature Closure of Fetal Ductus Arteriosus: Published literature reports that the use of NSAIDs at about 30 weeks of gestation and later in pregnancy may cause premature closure of the fetal ductus arteriosus.Oligohydramnios/Neonatal Renal Impairment: Published studies and postmarketing reports describe maternal NSAID use at about 20 weeks gestation or later in pregnancy associated with fetal renal dysfunction leading to oligohydramnios, and in some cases, neonatal renal impairment. These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation. In many cases, but not all, the decrease in amniotic fluid was transient and reversible with cessation of the drug. There have been limited number of case reports of maternal NSAID use and neonatal renal dysfunction without oligohydramnios, some of which were irreversible. Some cases of neonatal renal dysfunction required treatment with invasive procedures, such as exchange transfusion or dialysis.Methodological limitations of these postmarketing studies and reports include lack of control group; limited information regarding dose, duration, and timing of drug exposure; and concomitant use of other medications. These limitations preclude establishing reliable estimate of the risk of adverse fetal and neonatal outcomes with maternal NSAID use. Because the published safety data on neonatal outcomes involved mostly preterm infants, the generalizability of certain reported risks to the full-term infant exposed to NSAIDs through maternal use is uncertain. Animal dataCelecoxib at oral doses >=150 mg/kg/day (approximately times the human exposure at 200 mg twice daily as measured by AUC0-24), caused an increased incidence of ventricular septal defects, rare event, and fetal alterations, such as ribs fused, sternebrae fused and sternebrae misshapen when rabbits were treated throughout organogenesis. dose-dependent increase in diaphragmatic hernias was observed when rats were given celecoxib at oral doses >=30 mg/kg/day (approximately times human exposure based on the AUC0-24 at 200 mg twice daily for RA) throughout organogenesis. In rats, exposure to celecoxib during early embryonic development resulted in pre-implantation and post-implantation losses at oral doses >=50 mg/kg/day (approximately times human exposure based on the AUC0-24 at 200 mg twice daily for RA).Celecoxib produced no evidence of delayed labor or parturition at oral doses up to 100 mg/kg in rats (approximately 7-fold human exposure as measured by the AUC0-24 at 200 mg twice daily). The effects of celecoxib on labor and delivery in pregnant women are unknown.
