Question

Omeprazole is used in peptic ulcer – State reason

Q81 marksShort Answers

Answer

Omeprazole is a proton pump inhibitor. It irreversibly inhibits the H⁺/K⁺-ATPase (proton pump) on the luminal membrane of gastric parietal cells, which is the final common step of acid secretion. This produces profound and long-lasting suppression of both basal and stimulated gastric acid secretion, allowing healing of the peptic ulcer and relief of acid-related symptoms — hence its use in peptic ulcer disease.
