What is the first-line pharmacologic strategy to prevent NSAID-induced ulcers in patients who cannot discontinue NSAID therapy?

Explanation:
The main idea is protecting the gastric mucosa when a patient must continue NSAID therapy. NSAIDs inhibit COX-1 and deplete protective prostaglandins, increasing the risk of gastric and duodenal ulcers. Misoprostol is a synthetic prostaglandin E1 analog that directly replenishes these protective prostaglandins, boosting mucus and bicarbonate secretion, enhancing mucosal blood flow, and counteracting the acid- and NSAID-driven injury. Because it addresses the underlying deficit in mucosal defense caused by NSAIDs, misoprostol is the most appropriate first-line protective strategy for someone who cannot stop NSAIDs. Be aware that misoprostol can cause diarrhea and cramps and is contraindicated in pregnancy. Other options like proton pump inhibitors or H2 blockers reduce acid and are useful for gastroprotection, but they don’t restore prostaglandin-mediated mucosal defenses as misoprostol does. Sucralfate provides mucosal coating with variable efficacy.
