<h3>What is nitroglycerin?</h3>
Nitroglycerin is used to prevent chest pain (angina) that is caused by coronary artery disease. In addition, nitroglycerin is used to relieve an angina attack that is already occurring.
This medicine belongs to the group of nitrates (vasolidator medications). Nitroglycerin works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart while reducing its work load. When it is used regularly on a long-term basis, or right before exercise or a stressful event, it helps prevent angina attacks from occurring.
