Preventing or relieving a sudden attack of angina (chest pain) caused by heart disease. It may also be used for other conditions as determined by your doctor.
NitroQuick is a nitrate. It works by dilating (widening) blood vessels. Chest pain occurs when the heart needs more oxygen than it can get. Dilating blood vessels allows blood to flow more easily. This reduces the heart’s workload and the amount of oxygen needed by the heart.
