CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
The isosorbide mononitrate extended-release tablet is 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 capil
