Patient Education

Nitroglycerin Sublingual


Nitroglycerin sublingual tablets are used to treat episodes of angina (chest pain) in people who have coronary artery disease (narrowing of the blood vessels that supply blood to the heart). It is also used just before activities that may cause episodes of angina in order to prevent the angina from occurring. Nitroglycerin is in a class of medications called vasodilators. It works by relaxing the blood vessels so the heart does not need to work as hard and therefore does not need as much oxygen.
