Amlodipine, Verapamil, and Diltiazem are categorized under which class of drugs?

Amlodipine, Verapamil, and Diltiazem are all classified as calcium channel blockers. These drugs work by inhibiting the influx of calcium ions into the muscle cells of the heart and blood vessels. This action results in relaxed vascular smooth muscle, leading to dilation of peripheral arteries and a decrease in blood pressure. Additionally, they can reduce the heart rate and decrease myocardial contractility, making them effective in treating conditions like hypertension, angina, and certain types of arrhythmias.

Calcium channel blockers are particularly useful because they address cardiovascular issues from multiple angles, including reducing myocardial oxygen demand and allowing for improved blood flow. Understanding this classification is essential for recognizing their therapeutic uses and mechanisms of action in the clinical setting.
