Verapamil is classified as which type of drug?

Verapamil is classified as a calcium channel blocker, which is a type of medication that works by inhibiting the entry of calcium ions into cardiac and smooth muscle cells through voltage-gated calcium channels. This action leads to relaxation of vascular smooth muscle, resulting in vasodilation and a decrease in blood pressure. Additionally, verapamil has a significant effect on the cardiovascular system by reducing heart rate and contractility, which can also contribute to its antihypertensive effects.

Calcium channel blockers, including verapamil, are particularly effective in treating conditions like hypertension and angina due to their ability to relax the blood vessels and improve blood flow. They are distinct from other classes of antihypertensive medications, such as diuretics, ACE inhibitors, and beta-blockers, which work through different mechanisms. Understanding the classification of verapamil and its specific role within the category of calcium channel blockers can help in making informed decisions regarding treatment for hypertension and other cardiovascular conditions.
