WebNSAIDs inhibit prostaglandin synthesis by reversibly inhibiting cyclo-oxygenase (COX) enzymes — the two main types of COX enzyme are COX-1 and COX-2, which have different physiological functions. COX-1 produces prostaglandins that help to maintain gastric mucosal integrity and platelet-initiated blood clotting. Inhibition is thought to be ... WebInhibitors of prostaglandins. Prostaglandin synthesis is inhibited by two groups of anti-inflammatory agents: NSAIDs and GCs (the very same hormones elicited by stress). NSAIDs interfere only with COX activity; the prime example is aspirin, although indomethacin is routinely used in experimental systems.
