Oxaprozin Pathway


Oxaprozin is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties. Oxaprozin is used to treat rheumatoid arthritis, osteoarthritis, dysmenorrhea, and to alleviate moderate pain. Like most NSAIDs, oxaprozin is a non-selective prostaglandin G/H synthase (a.k.a. cyclooxygenase or COX) inhibitor that acts on both prostaglandin G/H synthase 1 and 2 (COX-1 and -2). COX catalyzes the conversion of arachidonic acid to a number of prostaglandins involved in fever, pain, swelling and inflammation. Oxaprozin antagonizes COX by binding to the upper portion of the active site, preventing its substrate, arachidonic acid, from entering the active site. The analgesic, antipyretic and anti-inflammatory effects of oxaprozin occurs as a result of decreased prostaglandin synthesis.
