Isosorbide Mononitrate is the mononitrate salt form of isosorbide, an organic nitrate with vasodilator activity. Isosorbide mononitrate relaxes vascular smooth muscle by formation of the free radical nitric oxide (NO), which is identical to the endothelium-derived relaxing factor (EDRF). NO activates guanylyl cyclase, thereby increasing the synthesis of cGMP within smooth muscle, resulting in dephosphorylation of light chain myosin and relaxation of peripheral arteries and veins. In addition, isosorbide mononitrate relaxes coronary arteries, thereby increasing the blood circulation through the ischemic area. (NCI05)
Isosorbide mononitrate is a Nitrate Vasodilator. The physiologic effect of isosorbide mononitrate is by means of Vasodilation.

4.2 Drug Indication

Isosorbide mononitrate is indicated for the prevention and management of angina pectoris due to coronary artery disease. The onset of action of oral isosorbide mononitrate is not sufficiently rapid to be useful in aborting an acute anginal episode.


FDA Label


5 Pharmacology and Biochemistry
5.1 Pharmacology

Isosorbide mononitrate is an anti-anginal agent and vasodilator that relaxes vascular smooth muscle to prevent and manage angina pectoris. The pharmacological action is mediated by the active metabolite, [nitric oxide], which is released when isosorbide mononitrate is metabolized. Nitric oxide works on both arteries and veins, but predominantly veins: by relaxing veins and reducing the central venous pressure, nitric oxide causes venous pooling and a decrease in the venous return to the heart, thus decreasing cardiac preload. In healthy subjects, the stroke volume is decreased and venous pooling can occur in the standing posture, leading to postural hypotension and dizziness. At therapeutic doses of isosorbide mononitrate, nitric oxide has a bigger effect on larger muscular arteries over small resistance arteries. Arterial relaxation leads to reduced systemic vascular resistance and systolic blood (aortic) pressure, decreasing to decreased cardiac afterload. The direct dilator effect on coronary arteries opposes the coronary artery spasm in variant angina or angina pectoris. At larger doses, nitric oxide causes the resistance arteries and arterioles to dilate, reducing arterial pressure via coronary vasodilatation. This leads to increased coronary blood flow. Reduced cardiac preload and afterload caused by nitric oxide causes a reduction in myocardial oxygen consumption; decreased myocardial oxygen demand, along with increased coronary blood flow, leads to an increased in the oxygen content of coronary sinus blood and the relief from ischemia. The end effect of isosorbide mononitrate include decreased cardiac oxygen consumption, redistribution coronary flow toward ischemic areas via collaterals, and the relief of coronary spasms. Nitric oxide can also increase the rate of relaxation of cardiac muscles, which is an effect outside of vascular smooth muscles. Organic nitrates can also relax other types of smooth muscles, including esophageal and biliary smooth muscle. The anti-anginal activity of isosorbide mononitrate was observed about 1 hour after dosing, and the peak effect was achieved from 1-4 hours after dosing. The duration of anti-anginal action of at least 12 hours was observed with an asymmetrical dosing regimen.

5.5 Absorption, Distribution and Excretion

Absorption

Upon oral administration, isosorbide mononitrate is rapidly and completely absorbed from the gastrointestinal tract. Isosorbide mononitrate has a dose-linear kinetics and the absolute bioavailability is nearly 100%. The Cmax is reached within 30 to 60 minutes following administration.


Route of Elimination

In a human radio-labelled drug study, about 93% of the total dose was excreted in the urine within 48 hours. Following oral administration of 20 mg, only 2% of isosorbide mononitrate was excreted unchanged in the urine within 24 hours. Among the excreted dose, nearly half of the dose was found de-nitrated in urine as isosorbide and sorbitol: approximately 30% is excreted as isosorbide and about 17% is the 2-glucuronide of mononitrate. These metabolites were not vasoactive or pharmacologically active. Renal excretion was complete after 5 days, and fecal excretion accounted for only 1% of drug elimination.


Volume of Distribution

The volume of distribution is approximately 0.6 L/kg, which is approximately the volume of total body water.


Clearance

The total body clearance is 115-120 mL/min.


5.6 Metabolism/Metabolites

Isosorbide mononitrate is not subject to first pass metabolism in human liver. Detectable metabolites include isosorbide, sorbitol, and 2-glucuronide of mononitrate, which are pharmacologically inactive.


5.7 Biological Half-Life

The elimination half-life of isosorbide mononitrate is about 5 hours. The elimination half-life of its metabolites, isosorbide and 2-glucuronide of mononitrate, are 8 hours and 6 hours, respectively.


5.8 Mechanism of Action

Isosorbide mononitrate acts as a prodrug for nitric oxide (NO), which is a potent vasodilator gas that is released when the drug is metabolized. NO activates soluble guanylyl cyclase in vascular endothelial cells, which increases the intracellular concentrations of cyclic GMP (cGMP). cGMP activates cGMP-dependent protein kinases, such as protein kinase G and I, which activates the downstream intracellular cascades. The downstream cascade results in reduced intracellular concentrations of calcium, caused by processes including inhibition of IP3-mediated pathway, phosphorylation of big calcium-activated potassium channel leading to cell hyperpolarization and reduced calcium influx, and increased calcium efflux via the Ca2+-ATPase-pump. Reduced intracellular calcium concentrations lead to the dephosphorylation of myosin light chains and the relaxation of smooth muscle cells.
