Drugs that block the entry of calcium into muscle cells, relaxing blood vessels and, for some, slowing the heart.
Calcium channel blockers stop calcium entering heart and vessel muscle: dihydropyridines (amlodipine) relax vessels (blood pressure); verapamil and diltiazem slow the heart and the AV node (rhythm, angina); dihydropyridines cause ankle swelling, verapamil causes constipation.
