Used in patients with heart failure. It can be used as emergency treatment in patients with cardiogenic shock. It can be used in anaesthesia when there is hypotension or bradycardia due to poor myocardial contractility.

==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.

==Vasopressin==
Vasopressin is a non-catecholamine vasopressor. It is a hypothalamic hormone found in the posterior pituitary. It promotes the renal reabsorption fo water as well as smooth muscle contraction particularly of capillaries and small arterioles. This smooth muscle contraction may lead to decreased blood flow to systems but increased hepatic blood flow. Vasporessin is indicated in patients with vasodilatory shock or ventricular fibrillation. However, possible side effects include vasconstriction and arrhythmias. It should be avoided in patients with vascular disease, history of seizures, heart failure, asthma or pregnant patients.
