This may be done in certain cases of heart failure when the blood pressure is too high and causing symptoms, and after surgery to lessen bleeding. It is administered continuously through a vein. Effects begin almost immediately and might continue for up to ten minutes. It has a history of triggering reflex tachycardia. In critical, urgent situations, it is frequently utilized as the preferred vasodilator. Nitric oxide is released from sodium nitroprusside, activating sodium guanylyl cyclase, which is related to pharmacological activation.
