Ismo (Isosorbide Mononitrate)

General Information

Ismo (Isosorbide Mononitrate) is indicated to prevent chest pain called angina. It is caused by reduced blood flow to the heart. It is usually 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.

How does Ismo (Isosorbide Mononitrate) work?

Ismo (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 the angina attacks. That it may happen when the heart does not get enough oxygen for the work it is doing.
