Curator's Comment: Description was created based on several sources, including https://www.oolac.com/dictionary/en/en/tag/Oxazoles and https://www.ncbi.nlm.nih.gov/pubmed/15934904

Oxaprozin is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties. Anti-inflammatory effects of Oxaprozin are believed to be due to inhibition of cylooxygenase in platelets which leads to the blockage of prostaglandin synthesis. Antipyretic effects may be due to action on the hypothalamus, resulting in an increased peripheral blood flow, vasodilation, and subsequent heat dissipation. Oxaprozin is a non-selective NSAID, with a cell assay system showing lower COX-2 selectivity implying higher COX-1 selectivity. Oxaprozin is used to treat rheumatoid arthritis, osteoarthritis, dysmenorrhea, and to alleviate moderate pain.
