Quizplus · Accepted Answer

Calcium channel blockers are the drug type of choice for Prinzmetal angina, chronic stable angina, hypertension, and supraventricular arrhythmias. They work by decreasing the amount of calcium entering the smooth muscle cells in the walls of blood vessels, which leads to vasodilation and increased blood flow to the coronary arteries. This helps relieve chest pain and reduce blood pressure.
