Uses for Gonitro

Nitroglycerin is used to prevent angina (chest pain) caused by coronary artery disease. This medicine is also used to relieve an angina attack that is already occurring.

Nitroglycerin belongs to the group of medicines called nitrates. It works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart while reducing its work load. When used regularly on a long-term basis, or just before exercise or a stressful event, this helps prevent angina attacks from occurring.

This medicine is available only with your doctor's prescription.
