Nitroglycerin, an organic nitrate, is a vasodilating agent that relieves tension on vascular smooth muscle and dilates peripheral veins and arteries. It increases guanosine 3'5' monophosphate (cyclic GMP) in smooth muscle and other tissues by stimulating guanylate cyclase through formation of free radical nitric oxide. This activity results in dephosphorylation of the light chain of myosin, which improves the contractile state in smooth muscle results in vasodilation.
