Medical uses
Nitroglycerin is used to treat chest pain (angina), and can also be used with other drugs to treat congestive heart failure and heart attacks. It works by relaxing the blood vessels to the heart (vasodilation, thereby increasing the blood flow and oxygen supply to the heart. Nitroglycerin can thus reduce chest pain but it does not cure the underlying causes.
