About Oxaprozin
Propionic acid derivative,NSAID,antiarthritic.
Mechanism of Action of Oxaprozin
Oxaprozin is a propionic acid derivative NSAID.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.
