Nitroglycerin is used to prevent chronic chest pain caused by heart disease. It is a nitrate. And it works by relaxing blood vessels. Chest pain can occur when the heart needs more oxygen than it can get. Relaxing blood vessels allows blood to flow more easily. And in this way it reduces heart's workload and the amount of oxygen the heart requires.
Take the medicine exactly as prescribed by your doctor.
