The mechanism of action of sodium nitroprusside is?
Ans. is 'b' i.e., Increases Guanyl Cyclase o "Nitroprusside dilates both aerial and venous vessels, resulting in reduced peripheral vascular resistance and venous return. The action occurs as a result of activation of guanylyl cyclase, either release of nitric oxide or by direct stimulation of enzyme. The result is increased intracellular cGMP, which relaxes vascular smooth muscle".
Increased cAMP
Increased guanylate cyclase
Calcium channel blockage
IC channel opener
