Osmosis video - cGMP mediated smooth muscle vasodilators

cGMP, or cyclic guanosine monophosphate, is a second messenger that mediates smooth muscle relaxation in response to various vasoactive agents such as nitric oxide (NO). cGMP-mediated smooth muscle vasodilators, are drugs that promote vasodilation by increasing the effect of cGMP. These drugs include hydralazine and nitroprusside, used to treat hypertension, and nitrates used to treat angina pectoris.
