Amlodipine is a medication used to treat high blood pressure (hypertension) in adults and children 6 years and older. It is also used to prevent chest pain caused by heart disease (angina) and coronary artery disease (narrowing of the blood vessels that supply blood to the heart) . Amlodipine belongs to a class of medications called calcium channel blockers, which work by relaxing blood vessels so blood can flow more easily. By doing so, it helps to prevent future heart disease, heart attacks, and strokes. Amlodipine is available as tablets or as a liquid you swallow, and it is usually taken once a day at the same time each day. It is important to note that amlodipine helps to control high blood pressure, angina, and coronary artery disease, but it does not cure these conditions.
