QUICK LINKS

Famprofazone is a non-steroidal anti-inflammatory chemical that functions as an inhibitor of cyclooxygenase, COX-1 and COX-2 enzymes. It exerts its mode of action by inhibiting the production of prostaglandins, which are lipid compounds involved in the response to injury and inflammation. By blocking the activity of the cyclooxygenase enzymes, famprofazone reduces the synthesis of prostaglandins from arachidonic acid, thereby diminishing the inflammatory response. Famprofazone′s mechanism of action involves binding to the active site of the cyclooxygenase enzymes, preventing the conversion of arachidonic acid to prostaglandins. This inhibition of prostaglandin synthesis results in the reduction of pain, fever, and inflammation. Famprofazone′s mode of action at the molecular level involves interfering with the enzymatic activity of cyclooxygenase, ultimately leading to the suppression of prostaglandin production.
