Nitroprusside is a vasodilator that works by relaxing the muscles in your blood vessels to help them dilate (widen). This lowers blood pressure and allows blood to flow more easily through your veins and arteries.
Nitroprusside is used to treat congestive heart failure and life-threatening high blood pressure (hypertension). Nitroprusside is also used to keep blood pressure low during a surgery.
Excessive hypotension, cyanide toxicity.
