Multiple Choice

Amlodipine is an antihypertensive medication.

Explanation:
The question tests drug class and mechanism for managing hypertension. Amlodipine is a calcium channel blocker used as an antihypertensive. It inhibits L-type calcium channels in vascular smooth muscle, causing dilation of arteries (vasodilation) and lowering peripheral resistance, which reduces blood pressure. This action is distinct from other drug types: antiarrhythmics modify cardiac rhythm, analgesics relieve pain, and mucolytics break down mucus. Amlodipine is specifically chosen for lowering blood pressure and can also help with angina, but it does not perform the roles of antiarrhythmic, analgesic, or mucolytic.
