2. Uses of Verapamil
2.1 Hypertension
Verapamil is commonly prescribed to treat high blood pressure, also known as hypertension. According to the American Heart Association, high blood pressure affects nearly half of all adults in the United States, putting them at risk for heart disease, stroke, and other serious health conditions. Verapamil works by relaxing the blood vessels, allowing for improved blood flow and lower blood pressure levels.
2.2 Angina
Another common use for verapamil is in the treatment of chest pain known as angina. Angina is caused by reduced blood flow to the heart muscle, leading to chest discomfort or pain. Verapamil helps dilate the coronary arteries, allowing for better blood flow to the heart and reducing angina symptoms. It is often used in combination with other medications to manage angina effectively.
2.3 Arrhythmias
Verapamil is also used to treat certain heart rhythm disorders, known as arrhythmias. These abnormalities in heart rhythm can lead to palpitations, fainting, and other symptoms. Verapamil helps regulate the heart’s electrical activity by slowing down the rate at which electrical signals travel through the heart muscle. This can help restore a normal heart rhythm and prevent complications associated with arrhythmias.
