What is the primary mechanism by which sodium nitroprusside exerts its effect?

Show Answers

Enhances cyclic AMP levelsActs as a direct vasodilatorInhibits calcium channelsSuppresses sympathetic activity in the hypothalamus

Explanation

Sodium nitroprusside works by directly relaxing the vascular smooth muscle, leading to vasodilation. It does not increase cAMP, block calcium channels, or influence sympathetic flow in the hypothalamus.
