Amlodipine and nifedipine belong to which drug class?

Explanation:
Calcium channel blockers reduce calcium entry into smooth muscle cells, which relaxes the vessels and lowers blood pressure. Amlodipine and nifedipine are in the dihydropyridine subgroup, meaning they mainly target vascular smooth muscle to produce arterial vasodilation with little direct effect on the heart's conduction system. This vasodilation lowers systemic vascular resistance and helps treat hypertension and angina. Other classes, like beta blockers, ACE inhibitors, and diuretics, work by different mechanisms (slowing heart rate, blocking angiotensin formation, or increasing fluid loss, respectively), so they’re not the same as these calcium channel blockers.
