Mechanism: additive vasodilation. Organic nitrate that causes systemic venodilation, decreasing preload; enters vascular smooth muscle and is converted to nitric oxide, leading to activation of cyclic guanosine monophosphate and vasodilation, Relaxes smooth muscle via dose-dependent dilation of arterial and venous beds to reduce both preload and afterload, as well as myocardial oxygen demand; also improves coronary collateral circulation, lowering blood pressure, increasing heart rate, and causing occasional paradoxical bradycardia, Bioavailability: Immediate release, 93-100%; extended release, 77-80%, Onset (antianginal effects): Immediate release, 60 min; extended release, 60 min, Onset (hemodynamic effects): Immediate release, 10-30 min; extended release, 6 hr, Duration (antianginal effects): Immediate release, 5-7 hr; extended release, 8 hr, Duration (hemodynamic effects): Immediate release, 10-30 min; extended release, 6 hr, Peak plasma time: Immediate release, 30-60 min; extended release, 3-4.5 hr, Metabolites: Isosorbide, 5-isosorbide mononitrate glucuronide, sorbitol (inactive), Half-life: Parent drug, 6.2-6.6 hr; glucuronide metabolite, 6 hr; sorbitol metabolite, 9 hr.
