NCIt definition : A propionic acid derivate and nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory,
analgesic and antipyretic effects. Ketoprofen inhibits the activity of the enzymes
cyclo-oxygenase I and II, resulting in a decreased formation of precursors of prostaglandins
and thromboxanes. The resulting decrease in prostaglandin synthesis, by prostaglandin
synthase, is responsible for the therapeutic effects of ibuprofen. Ketoprofen also
causes a decrease in the formation of thromboxane A2 synthesis, by thromboxane synthase,
thereby inhibiting platelet aggregation.;
