Nitroprusside sodium — Uses, Dosage, Side Effects & Safety
Drug class: Vasodilator; Antihypertensive agent
Overview
Nitroprusside sodium is a fast-acting medication used to quickly lower dangerously high blood pressure (hypertensive emergencies) and to manage acute heart failure. It is given by intravenous (IV) infusion in a hospital setting, where your heart and blood pressure can be closely monitored. This medicine works by relaxing the muscles in your blood vessels, causing them to widen (vasodilation). This helps blood flow more easily, reduces blood pressure, and decreases the workload on the heart. Key points: Nitroprusside sodium is only used under strict medical supervision due to its potency and risk of side effects. It is not for home use and is typically reserved for emergencies or when other blood pressure medications are not effective.
