Quizplus · Accepted Answer

Histamine antagonists, also known as H2 blockers or H2-receptor antagonists, work by blocking the action of histamine on gastric parietal cells, which are responsible for the secretion of hydrochloric acid (HCl) in the stomach. By inhibiting HCl secretion, histamine antagonists can help reduce the acidity of the stomach and improve symptoms of peptic ulcer disease. Choice A is incorrect because histamine antagonists do not affect gastric motility. Choice B is incorrect because they do not inhibit secretion of pepsinogen, which is produced by chief cells rather than parietal cells. Choice C is incorrect because they do not neutralize gastric acid, but rather reduce its production.
