Norepinephrine (Levophed)
-Potent vasoconstrictor
-Used to treat: Hypotension, Cardiac arrest
Dopamine hydrochloride(Intropin)
-The immediate precursor of norepinephrine
-Dosage effects: Low doses cause renal perfusion, Low to moderate doses cause increasd cardiac output, Higher doses increase peripheral resistance and blood pressure
Dobutamine hydrochloride (Dobutrex)
-A synthetic catecholamine
-Acts directly on the heart muscle to increase the force of contraction
