Ans) Both enzymes produce prostaglandins that promote inflammation, pain, and fever; however, only COX-1 produces prostaglandins that activate platelets and protect the stomach and intestinal lining. Nevertheless, COX-2 inhibitors are as effective as the older NSAIDs for treating inflammation, pain and fever.

- NSAIDs block the COX enzymes and reduce production of prostaglandins. Therefore, inflammation, pain, and fever are reduced by all COX inhibitors. Since the prostaglandins that protect the stomach and promote blood clotting also are reduced, NSAIDs can cause ulcers in the stomach and intestines, and increase the risk of bleeding. Unlike older NSAIDs that block both COX-1 and COX-2, the newer COX-2 inhibitors only block the COX-2 enzyme. Since COX-2 inhibitors do not block COX-1 (which primarily produces prostaglandins that protect the stomach and promote blood clotting) they do not cause ulcers or increase the risk of bleeding as much as the older NSAIDs. Nevertheless, COX-2 inhibitors are as effective as the older NSAIDs for treating inflammation, pain and fever.
