Calcium channel blockers: What to know

Calcium channel blockers are a type of medication that people take to increase the flow of blood and oxygen to the heart. Doctors may prescribe a calcium channel blocker to treat high blood pressure or a variety of heart conditions.
Calcium channel blockers are common medications that have a low risk of complications. In this article, we discuss how these drugs work, as well as their uses and possible side effects.

What is a calcium channel blocker?

Calcium is necessary for muscle contractions to occur throughout the body. This mineral enters muscle cells through ion channels, which are tiny pores on the surface of the cell. This process is essential for normal bodily functioning.
Calcium channel blockers reduce the amount of calcium that can enter muscle cells in the heart and blood vessel walls via these channels.
In doing this, they lower the pressure in the blood vessels and on the heart.

Uses

Doctors commonly use calcium channel blockers to treat high blood pressure. These drugs also have a range of other possible uses, such as for:
1.chest pain, or angina
3.an irregular heartbeat, or arrhythmia
Scientists are currently exploring other potential uses for calcium channel blockers. For example, by reducing high blood pressure, they believe that calcium channel blockers may be able to lower the risk of Alzheimer's disease.
