is nitroprusside a beta blocker
Nitroprusside is light sensitive; both bottle and tubing should be wrapped in aluminum foil. Before initiating nitroprusside, administer a beta-blocker to counteract the physiologic response of reflex tachycardia that occurs when nitroprusside is used alone.This physiologic response increases shear forces against the aortic wall, thus increasing dP/dt. The objective is to keep the heart rate at 60-80 bpm.etoprolol (Lopressor, Toprol XL). Metoprolol is a selective beta1-adrenergic receptor blocker that decreases the automaticity of contractions. During IV administration, carefully monitor the blood pressure, heart rate, and electrocardiogram (ECG).
