Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)

Cox B 200 mg is a nonsteroidal anti-inflammatory drug that exhibits anti-inflammatory, analgesic and antipyretic activities. The mechanism of action of Cox B 200 mg is believed to be due to inhibition of prostaglandin synthesis, primarily via inhibition of cyclooxygenase-2 (COX-2) and at therapeutic concentrations in humans, Cox B 200 mg does not inhibit the cyclooxygenase-1 (COX-1) isoenzyme.

ACE inhibitors: Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE inhibitors. This interaction should be given into consideration in patients taking Cox B 200 mg concomitantly with ACE inhibitors. Frusemide: NSAIDs can reduce the natriuretic effect of Frusemide and thiazides in some patients. Aspirin: Cox B 200 mg can be used with low dose Aspirin. However, concomitant administration of Aspirin with Cox B 200 mg may result in an increased rate of gastrointestinal ulceration or similar complications, compared to the use of Cox B 200 mg alone. Fluconazole: Concomitant administration of Fluconazole at 200 mg qid resulted in a two fold increase in Cox B 200 mg plasma concentration. Cox B 200 mg should be introduced at the lowest recommended dose in patients receiving Fluconazole. Lithium: Patients on Lithium treatment should be closely monitored when Cox B 200 mg is introduced or withdrawn. Warfarin: Caution should be used when administering Cox B 200 mg with Warfarin since these patients are at increased risk of bleeding complications. Co-administration of Cox B 200 mg with aluminium and magnesium-containing antacid should be avoided, because they may reduce the amount of Cox B 200 mg that the body absorbs.

Cox B 200 mg should be used during pregnancy only if the potential benefit justifies the potential risk to fetus. But in late pregnancy Cox B 200 mg should be avoided because it may cause premature closure of ductus arteriosus. It is not known whether Cox B 200 mg is excreted in human milk. Because many drugs are excreted in human milk and because of potential for serious adverse reactions in nursing infants from Cox B 200 mg, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Cox B 200 mg, at doses up to 200 mg bid, can be administered without regard to timing of meal. Higher doses (400 mg bid) should be administered with food.

Patients should be managed by symptomatic and supportive care following an NSAID overdose. There are no specific antidotes. No information is available regarding the removal of Cox B 200 mg by hemodialysis but based on its high degree of plasma protein binding (>97%) dialysis is unlikely to be useful in overdose. Emesis and/or activated charcoal and/or osmotic cathartic may be indicated in patients seen within 4 hours of ingestion with symptoms or following a large overdose. Forced diuresis, alkalinization of urine, hemodialysis or hemoperfusion may not be useful due to high protein binding.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Geriatric: 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.Paediatric: The safety and efficacy of Cox B 200 mg is not established in paediatric patients.Hepatic insufficiency: Cox B 200 mg should be introduced at a reduced dose in patients with moderate hepatic impairment. The use of Cox B 200 mg in patients with severe hepatic impairment is not recommended.
