Cardene, also known as nicardipine, is a medication used to treat high blood pressure (hypertension). Nicardipine can also be used to prevent chest pains and lower your risk for heart attack. Nicardipine is a calcium channel blocker that works by relaxing blood vessels so the heart does not have to pump as hard. Chest pain is controlled by increasing the supply of blood and oxygen to the heart.
