In which aspect, Salicylate is different from NSAIDs? [Select ALL THAT APPLY]
a. May provide greater pain control with equivalent doses.
b. May cause more GI side effects than NSAIDs.
c. Inhibits prostaglandin synthesis irreversibly; where NSAIDs do reversibly.
d. May cause more renal damage than NSAIDs.
e. May increase the risk of bleeding more compared to NSAIDs.
Answer (b,c): Salicylates, like NSAIDs, work by inhibiting prostaglandin synthesis by inhibiting both COX-1 and COX-2 enzymes; however, salicylates do so in an irreversible manner, while NSAIDs do so reversibly.
