Uses

Isosorbide mononitrate belongs to a group of drugs called nitrates. It dilates (widens) blood vessels, making it easier for blood to flow through them and easier for the heart to pump. Isosorbide mononitrate is used to prevent angina attacks (chest pain). Isosorbide mononitrate will not treat an angina attack that has already begun.
