COX-2 Inhibitors: What They Are, Uses & Side Effects - Cleveland Clinic

WebAspirin is an irreversible cyclooxygenase-1 (COX-1) inhibitor that modifies the enzymatic activity of cyclooxygenase-2 (COX-2). This is in contrast to other NSAIDs like ibuprofen/naproxen that bind to this enzyme reversibly. Moreover, it permanently inhibits thromboxane A2 on platelets, blocking platelet aggregation. WebAlthough COX-1 inhibitors (blockers) block inflammation, they also block the helpful effects — the stomach and intestinal lining protection and blood clotting control. COX-2 enzymes make prostaglandins that are mainly involved in inflammation. COX-2 inhibitors mostly block inflammation. COX-2 inhibitors don’t block COX-1 enzymes. canaca blend 19 strain
