Overview
Isosorbide mononitrate is a drug used principally in the treatment of angina pectoris and acts by dilating the blood vessels so as to reduce the blood pressure. It is sold in the USA by Kremers Urban under the trade name Monoket, also sold in the USA under the name Imdur, and marketed in the UK under the trade names: Monosorb, Chemydur. In India, this drug is available under the brand names of Ismo, Isonorm, Monotrate, Solotrate, and Monit.

Mechanism of Action
ISMN extended-release tablets are an oral extended-release formulation of ISMN, the major active metabolite of isosorbide dinitrate; most of the clinical activity of the dinitrate is attributable to the mononitrate.
The principal pharmacological action of ISMN and all organic nitrates in general is relaxation of vascular smooth muscle, producing dilatation of peripheral arteries and veins, especially the latter. Dilatation of the veins promotes peripheral pooling of blood, decreases venous return to the heart, thereby reducing left ventricular end-diastolic pressure and pulmonary capillary wedge pressure (preload). Arteriolar relaxation reduces systemic vascular resistance, and systolic arterial pressure and mean arterial pressure (afterload). Dilatation of the coronary arteries also occurs. The relative importance of preload reduction, afterload reduction, and coronary dilatation remains undefined.[1]
