Pharmacology

Oxaprozin, the potassium salt of oxaprozin, is a nonsteroidal anti-inflammatory drug (NSAID), which dissociates into the active moiety oxaprozin in vivo. 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 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. Because oxaprozin potassium is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.

Dosage & Administration

Important:
Do not take any medication without a doctor's prescription. Self-medication can be dangerous.
General Dosing Instructions: Carefully consider the potential benefits and risks of Oxaprozin and other treatment options before deciding to use Oxaprozin. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals. After observing the response to initial therapy with Oxaprozin, the dose and frequency should be adjusted to suit an individual patient’s needs.

Divided doses may be tried in patients unable to tolerate single doses. For osteoarthritis patients of low body weight or with milder disease, an initial dose of one 600 mg tablet once a day may be appropriate. The maximum total daily dose is 1200 mg.
