NCIt definition : The potassium salt form of oxaprozin and a member of the propionic acid group of non-steroidal
anti-inflammatory drugs (NSAIDs) with anti-inflammatory, analgesic and antipyretic
properties. Oxaprozin potassium reversibly and competitively inhibits cyclooxygenases
(COX), thereby blocking the conversion of arachidonic acid to pro-inflammatory prostaglandins.
This inhibits the formation of prostaglandins that are involved in pain, inflammation
and fever.;
