OXAPROZIN MODE OF ACTION
Oxaprozin has analgesic, anti-inflammatory, and antipyretic properties. The mechanism of action of Oxaprozin, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Oxaprozin is a potent inhibitor of prostaglandin synthesis in vitro.
Oxaprozin is indicated:
- For relief of the signs and symptoms of osteoarthritis
- For relief of the signs and symptoms of rheumatoid arthritis
- For relief of the signs and symptoms of juvenile rheumatoid arthritis
For OA, the dosage is 1200 mg given orally once a day.
For RA, the dosage is 1200 mg given orally once a day.
Juvenile Rheumatoid Arthritis
For JRA, in patients, 6 to 16 years of age, the recommended dosage is given orally once per day should be based on the bodyweight of the patient as given in
Oxaprozin is contraindicated in the following patients:
Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to oxaprozin or any components of the drug product
History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients
In the setting of CABG surgery
Oxaprozin and anticoagulants such as warfarin have a synergistic effect on bleeding. The concomitant use of oxaprozin and anticoagulants have an increased risk of serious bleeding compared to the use of either drug alone.
Concomitant use of oxaprozin and analgesic doses of aspirin is not generally recommended because of the increased risk of bleeding
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 oxaprozin with diuretics, observe patients for signs of worsening renal function, in addition to assuring diuretic efficacy including antihypertensive effects
The concomitant use of oxaprozin with digoxin has been reported to increase the serum concentration and prolong the half-life of digoxin.
NSAIDs have produced elevations in plasma lithium levels and reductions in renal lithium clearance. The mean minimum lithium concentration increased by 15%, and the renal clearance decreased by approximately 20%. This effect has been attributed to NSAID inhibition of renal prostaglandin synthesis.
Concomitant use of NSAIDs and methotrexate may increase the risk for methotrexate toxicity (e.g., neutropenia, thrombocytopenia, renal dysfunction) because NSAID administration may result in increased plasma levels of methotrexate, especially in patients receiving high doses of methotrexate.
Concomitant use of oxaprozin and cyclosporine may increase cyclosporine’s nephrotoxicity.
Concomitant use of oxaprozin with other NSAIDs or salicylates (e.g., diflunisal, salsalate) increases the risk of GI toxicity, with little or no increase in efficacy.
Concomitant use of oxaprozin and pemetrexed may increase the risk of pemetrexed-associated myelosuppression, renal, and GI toxicity (see the pemetrexed prescribing information).
Concomitant use of corticosteroids with oxaprozin may increase the risk of GI ulceration or bleeding.
While oxaprozin does alter the pharmacokinetics of glyburide, co-administration of oxaprozin to type II non-insulin-dependent diabetic patients did not affect the area under the glucose concentration curve nor the magnitude or duration of control.

Reporting of suspected adverse reactions:
The PPB Department of Pharmacovigilance was set up with a vision to develop, implement and continuously upgrade an appropriate system for detecting, reporting, and monitoring adverse drug reactions (ADRs) and other relevant problems with medicines in Kenya. The department strives to ensure the safety and efficacy of pharmaceutical products in Kenya.
Reporting suspected adverse reactions after authorization of the medicinal product are important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals/ Patients are encouraged to report any suspected adverse reactions via Pharmacovigilance Yellow Form, firstname.lastname@example.org or clicking below button:
