What Is Verapamil?

Verapamil is a member of the class of medications called calcium channel blockers. It is a drug that relaxes the heart muscles and blood vessels so that the heart is not required to pump as much. Verapamil can also increase the flow of oxygen and blood to the heart and reduce heart electrical activity to control heart rate.

Verapamil is a treatment for hypertension (high blood pressure), angina (chest pain), as well as certain heart rhythm disorders.The tablets with immediate release can also be taken in combination with other medications to stop and treat irregular heartbeats.Verapamil injections are administered to children and adults to quickly and briefly restore normal heart rhythm for people suffering from specific heart rhythm problems.

A high level of blood pressure (hypertension) is a frequent problem that, if not addressed, can result in damage to the heart, brain, kidneys, blood vessels, and other areas of the human body. Organ damage can cause heart disease, a heart attack, a stroke, heart failure, kidney problems, loss of vision, and other issues. Alongside taking medications, changing your lifestyle will aid in controlling your blood pressure. This includes eating a balanced diet low in salt and fat and keeping a healthy weight, exercising for at least 30 minutes on a daily basis while not smoking, and drinking alcohol only in moderate amounts.
