What is nitroglycerin?
Nitroglycerin is a prescription medication used to prevent angina (chest pain) symptoms caused by coronary artery disease. It may also be used to reduce symptoms of an angina attack that is already happening. Nitroglycerin is administered in a number of ways. It can be prescribed as a sublingual tablet, powder, or extended-release tablet. It may also be prescribed as a topical gel or ointment.
It is important to note that nitroglycerin is not a cure for angina symptoms. Instead, it helps prevent their occurrence, while helping patients manage them when they do flare up.
