Isosorbide Dinitrate is an organic nitrate that shows vasodilator activity. This ingredient relaxes the vascular smooth muscle by the production of the free radical nitric oxide. It is identical to the endothelium-derived relaxing factor. This free radical of NO activates guanylyl cyclase so as to increase the synthesis of cGMP within a muscle. It results in the relaxation of peripheral arteries and veins. It also relaxes coronary arteries to increase blood circulation through the ischemic area. This active component is a nitrate vasodilator available as a conventional tablet form.
