Nitroglycerin is a vasodilator, a medicine that opens blood vessels to improve blood flow. It is used to treat angina symptoms, such as chest pain or pressure, that happens when there is not enough blood flowing to the heart. To improve blood flow to the heart, nitroglycerin opens up (dilates) the arteries in the heart (coronary arteries), which improves symptoms and reduces how hard the heart has to work. Nitroglycerin comes in quick-acting forms and long-acting forms.

Nitroglycerin is used for: Treating high blood pressure during surgery, controlling congestive heart failure associated with heart attack, treating chest pain in certain patients, and lowering blood pressure during surgery. Nitroglycerin is a nitrate. It works by relaxing (widening) blood vessels. Chest pain occurs when the heart needs more oxygen than it can get. Relaxing blood vessels allows blood to flow more easily. This reduces the heart's workload and the amount of oxygen needed by the heart.

In patients with angina, nitroglycerin preferentially dilates blood vessels that supply the areas of the heart where there is not enough blood flow and oxygen thereby delivering oxygen to the heart muscle that needs it most.

Quick-acting forms of nitroglycerin are used to relieve angina or used just before activities that typically cause angina. The quick-acting forms include tablets or oral sprays. The tablets are placed under the tongue (sublingual) or between the cheek and gum (buccal). The spray is used on or under the tongue.

The production of energy requires oxygen. Angina pectoris (angina) or heart pain is due to an inadequate flow of blood (and oxygen) to the muscle of the heart. It is believed that all nitrates, including nitroglycerin, have their effects by dilating (widening) the arteries and veins throughout the body.
