NSAIDs analgesia primarily by inhibiting which enzymes?

Explanation:
NSAIDs relieve pain mainly by blocking cyclooxygenase enzymes. These enzymes convert arachidonic acid into prostaglandins, which sensitize nerves and drive inflammation. By inhibiting COX-1 and COX-2, NSAIDs lower prostaglandin production, reducing pain signaling and inflammation. COX-1 is involved in protective gastric and platelet functions, while COX-2 is mainly induced during inflammation, which helps explain both the analgesic effects and some side effects. The other enzymes listed don’t drive the main analgesic effect: lipoxygenase leads to leukotrienes, phosphodiesterase affects cyclic nucleotides, and kinases regulate many cellular processes but are not the primary targets of NSAIDs for pain relief.
