Amlodipine besylate, commonly known as Norvasc, is prescribed to relieve episodes of angina, which is a condition that produces severe pain in the chest. This pain is normally caused by clogged arteries that cause a lack of oxygen in the heart. However, it can also be prescribed to treat high blood pressure.
The medication is classified as a calcium channel blocker. This allows the medication to dilate the blood vessels. This slows the heart, which allows the blood pressure to be reduced. As a result, it relieves the pain of angina .
