Nifedipine, Verapamil, and Diltiazem are all considered which type of hypertensive medication?

Explanation:
Calcium channel blockers. They work by blocking L-type calcium channels in vascular smooth muscle and cardiac muscle, which reduces calcium entry and leads to relaxation of arteries (vasodilation) and, with some agents, decreased heart rate and slower conduction. Nifedipine mainly dilates arteries, Verapamil and Diltiazem add more direct effects on the heart, but all three share the same mechanism, distinguishing them from beta blockers, ACE inhibitors, and diuretics.
