Physicians often prescribe calcium channel blockers to patients diagnosed with hypertension, especially those over 55 years of age, people of African or Caribbean descent, or people with diabetes. Calcium channel blockers can also treat circulatory conditions such as Raynaud’s disease. Medical professionals often choose them to treat chest pain or irregular heartbeat. Not only do these medications have modest side effects, but they are usually a safe option for pregnant and nursing mothers and older individuals.


1. How Calcium Channel Blockers Work

Calcium is crucial for the regulation of heart-muscle functions and nerve transmission. It is an important element for the heart’s contraction mechanism, which supplies blood to the body. However, for some individuals, excessive calcium causes the heart to contract in a more robust manner, allowing higher levels of calcium to flow through the vessels, causing hypertension. Calcium channel blockers or CCBs slow the rate at which calcium passes into the heart muscle and the blood vessel walls. As a result, the vessels relax and allow the blood to flow more easily. There is less demand for oxygen from the heart, which thus lowers blood pressure.
