Alters physiology: These are very simple answers to a complex question. Levophed (norepinephrine) increases blood pressure; Dopamine increases heart rate, blood pressure and cardiac function (contractility); Dobutamine increases cardiac contractility and heart rate.

Specializes in

Pressors & inotropes: Levophed (norepinephrine) causes blood vessels to constrict & is mainly used to increase blood pressure (pressor). Dobutamine helps the heart contract more forcefully & increase cardiac output (inotrope); it also can cause the blood vessels to dilate. Dobutamine is both a pressor & an inotrope--it makes blood vessels to constrict, & it increases cardiac output by causing the heart to beat faster & stronger.
