Patient Education

Nitroglycerin Transdermal Patch


Nitroglycerin transdermal patches are used to prevent episodes of angina (chest pain) in people who have coronary artery disease (narrowing of the blood vessels that supply blood to the heart). Nitroglycerin transdermal patches can only be used to prevent attacks of angina; they cannot be used to treat an attack of angina once it has begun. Nitroglycerin is in a class of medications called vasodilators. It works by relaxing the blood vessels so that the heart does not need to work as hard and therefore does not need as much oxygen.
