Isosorbide mononitrate is a nitrate that dilates coronary arteries and peripheral veins. It acts by releasing nitric oxide, which activates guanylate cyclase, increasing cGMP levels, leading to smooth muscle relaxation and vasodilation.
Isosorbide mononitrate is a vasodilator that relaxes vascular smooth muscle via the release of nitric oxide (NO), which activates guanylate cyclase, increasing intracellular cGMP. This leads to venous and arterial dilation, reducing preload and afterload, thereby decreasing myocardial oxygen demand.
20 mg orally twice daily, 7 hours apart (e.g., 8 AM and 3 PM) to minimize nitrate tolerance.

Terminal elimination half-life is approximately 5-6 hours. In elderly patients or those with hepatic impairment, half-life may be prolonged (up to 8-10 hours), warranting dose adjustment.
Terminal elimination half-life is approximately 5 hours (range 4–6 hours) for isosorbide mononitrate, consistent with a sustained duration suitable for once-daily dosing.
Primarily renal; 80-90% of the dose is excreted as inactive metabolites (isosorbide mononitrate and isosorbide dinitrate) in urine. Less than 1% is excreted unchanged. Fecal excretion is minimal.
Renal: approximately 98% of the dose is excreted in urine as metabolites (isosorbide mononitrate and its glucuronide conjugates); fecal excretion is minimal (<2%).
