FAQ - What do nitroglycerites do?

Nitroglycerin is a drug that has been used for many years to relieve symptoms of angina. It works by dilating or opening up coronary arteries that are partially blocked. It can relieve symptoms of angina within a few minutes. If you have to take nitroglycerin more frequently than usual, it may be a sign the heart disease has worsened and you should seek medical advice in that case.
