Isosorbide is used to prevent chest pain (angina) and reduce strain on the heart in patients with heart disease (coronary artery disease). Isosorbide mononitrate relaxes and widens blood vessels so blood can flow more easily. This medication will not relieve chest pain once it occurs. This medication may also be used in addition to other drugs to improve the symptoms of congestive heart failure (e.g., trouble breathing).
