What is nitroprusside?
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.
Nitroprusside may also be used for purposes other than those listed in this medication
guide.
