Question

Quizplus · Accepted Answer

Zantac and Tagamet are both H2-histamine receptor antagonists, which means they block the H2 receptors in the stomach lining that stimulate acid production. By blocking these receptors, they reduce the amount of acid produced in the stomach, which can help relieve symptoms of gastritis and ulcers. Option A is correct because it accurately describes the mechanism of action of these drugs. Option B is incorrect because there is no such thing as an H1-histamine receptor. Option C is incorrect because drugs that inhibit proton pumps, such as proton pump inhibitors (PPIs), work by a different mechanism than H2-receptor antagonists. Option D is incorrect because Zantac and Tagamet do not have antibacterial properties and do not kill bacteria.
