GENERIC NAME: isosorbide mononitrate

BRAND NAMES: Imdur (discontinued brand), Ismo (discontinued brand), Monoket

DRUG CLASS AND MECHANISM: Isosorbide mononitrate is in the class of drugs called nitrates that are used for treating and preventing angina. Other nitrates include nitroglycerin (Nitrostat, NitroQuick, Nitrolingual, Nitro-Dur and others) and isosorbide dinitrate (Isordil Titradose, Dilatrate-SR, Isochron). Nitrates are vasodilators (dilators of blood vessels). Blood returning from the body in the veins must be pumped by the heart through the lungs and into the body's arteries against the high pressure in the arteries. In order to accomplish this work, the heart's muscle must produce and use energy ("fuel") which requires oxygen brought to the heart by the blood. The FDA approved isosorbide mononitrate in December 1991.
