Mechanism of Action

Isosorbide mononitrate relaxes vascular smooth muscles by stimulating cyclic-GMP. It decreases left ventricular pressure (preload) and arterial resistance (afterload). Onset: 20 min (oral as conventional tab). Duration: 8-10 hr (oral as conventional tab). Absorption: Readily absorbed from the GIT (oral); peak plasma concentrations after 1 hr. Distribution: Widely distributed: Smooth muscle cells of the blood vessels. Metabolism: Converted to inactive metabolites including isosorbide and isosorbide glucuronide. Excretion: Via urine (2% as unchanged); 4-5 hr (elimination half-life).

Special Precautions

Severe renal or severe hepatic impairment, hypothyroidism, malnutrition, or hypothermia. Caution in patients who are already hypotensive. May aggravate angina caused by hypertrophic cardiomyopathy. Tolerance may develop after long-term treatment. Lactation.
