Which medication is a calcium channel blocker used to treat hypertension?

Explanation:
Calcium channel blockers lower blood pressure by preventing calcium from entering vascular smooth muscle cells, which causes the vessels to relax and dial down systemic resistance. Nifedipine is a dihydropyridine calcium channel blocker that mainly dilates arterial smooth muscle, producing a clear drop in blood pressure and making it a common choice for hypertension (and angina). The other drugs aren’t calcium channel blockers: enalapril and ramipril are ACE inhibitors that reduce angiotensin II formation, while clonidine lowers blood pressure by decreasing sympathetic outflow. So nifedipine is the best match for a calcium channel blocker used to treat hypertension.
