    Nitroglycerin is in a class of medications called vasodilators. It is used to treat congestive heart failure, to help prevent frequent chest pain caused by a heart condition known as angina, and to relieve pain caused by chronic anal fissures. It works by causing your veins to expand or dilate, known as venodilation. It also works on dilating the coronary arteries, contributing to the relief of angina. By doing so, the heart does not need to work as hard and therefore does not need as much oxygen.

    Nitroglycerin comes as a sublingual tablet to take under the tongue. The tablets is usually taken as needed, either 5 to 10 minutes before activities that may cause attacks of angina or at the first sign of an attack.
