DESCRIPTION
Isosorbide mononitrate (ISMN), an organic nitrate and the major
biologically active
metabolite of isosorbide dinitrate (ISDN), is a vasodilator with
effects on both arteries
and veins.
Each tablet, for oral administration, contains either 30 mg, 60 mg or
120 mg of
isosorbide mononitrate in an extended-release formulation. In
addition, each tablet
contains the following inactive ingredients: colloidal silicon
dioxide, hydrogenated castor
oil, hypromellose, lactose monohydrate, magnesium stearate,
microcrystalline cellulose
and talc.
The molecular formula of ISMN is C
H
NO
and the molecular weight is 191.14. The
chemical name for ISMN is 1,4:3,6-dianhydro-,D-glucitol 5-nitrate; the
compound has the
following structural formula:
ISMN is a white, crystalline, odorless compound which is stable in air
and in solution, has
a melting point of about 90°C, and an optical rotation of +144° (2%
in water, 20°C).
Isosorbide mononitrate is freely soluble in water, ethanol, methanol,
chloroform, ethyl
acetate, and dichloromethane.

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, systolic arterial pressure and
mean arterial
pressure (afterload). Dilatation o
