Dobutamine has a low half life and so is given via a continuous rate intravenous infusion. Due to its potential side effects however, it can only be administered for a maximum of 48 hours.

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.

Vasopressin is a non-catecholamine vasopressor. It is a hypothalamic hormone found in the posterior pituitary which promotes renal reabsorption of water as well as smooth muscle contraction particularly of capillaries and small arterioles. This smooth muscle contraction may lead to decreased blood flow to internal body systems but increased hepatic blood flow.
