==Dopamine==

==Dopamine==

Dopamine is a noradrenaline precursor which acts on both α and β cardiac receptors, as well as dopaminergic receptors found peripherally. It is a positive inotrope. It is very similar to dobutamine in action. It should be administered via a continuous rate infusion. It is used short term for patients with systolic dysfunction as well as management of oliguric renal failure. It can be used as a pressor agent to help treat inappropriate hypotension in concious and anaesthetised patients.

==Ephedrine==

==Ephedrine==

'''Ephedrine''' has the same action as epinephrine but has slightly different properties. It is similar to amphetamines in that ephedrine causes noradrenaline release leading to catecholaminergic receptor stimulation. Ephedrine has a lower potency but longer duration of action when compared with epinephrine. It also has more pronounced CNS effects.
