Isosorbide Mononitrate

What condition does Isosorbide Mononitrate treat?

Isosorbide Mononitrate is used to prevent chest pain called angina. Angina is caused by reduced blood flow to the heart. It usually occurs in patients with a certain heart condition called coronary artery disease.

Coronary artery disease is the blockage or narrowing of the coronary arteries. It is usually caused by atherosclerosis. Atherosclerosis is the build-up of cholesterol and fatty deposits on the inner wall of the arteries. It is also sometimes called clogging or hardening of the arteries.

Isosorbide Mononitrate is a type of medicine called nitrate. Organic nitrates are vasodilators that are active in both arteries and veins. This medication comes as a tablet for oral use. This was approved by the Food and Drug Administration (FDA).

How does Isosorbide Mononitrate work?

Isosorbide Mononitrate works by relaxing and widening blood vessels. It is both in the heart and around the body.

Widening the veins lessens the volume of blood that returns to the heart with each heartbeat. It is to make for the heart to pump the blood out again easier. Widening the arteries around the body also lowers the resistance that the heart has to pump against. These effects mean that the heart does not need to use as much energy to pump the blood around the body. Therefore, it needs less oxygen.

By widening the arteries within the heart itself, this medication also improves the oxygen and blood supply to the heart muscle. These actions, allow the medicine to prevent angina attacks. It might occur when the heart does not get enough oxygen for the work it is doing.
