Imdur (Isosorbide mononitrate) is a prescription medication used to prevent chest pain (angina) in patients with coronary artery disease. Coronary artery disease is caused by plaque buildup in the arteries supplying blood to the heart. The plaque buildup causes the insides of the coronary arteries to narrow over time. The drug will only prevent angina attacks. It will not treat an angina attack that has already begun. The active ingredient in Imdur is Isosorbide mononitrate. Isosorbide mononitrate belongs to a class of drugs called Nitrates. It works by dilating the blood vessels, making blood flow easier and making it easier for the heart to pump blood.
