Metaraminol, also known as metaradrine and sold under the brand names Aramine and Pressonex among others, is a sympathomimetic medication which is used in the prevention and treatment of hypotension (low blood pressure), particularly as a complication of anesthesia.[1][4][5] It is given by intramuscular or intravenous administration.[1][2]

Side effects of metaraminol include reflex bradycardia among others. Metaraminol is a norepinephrine releasing agent and at high doses a α1-adrenergic receptor agonist with some β-adrenergic effect.[6][7][8] It is a substituted amphetamine and is closely related to phenylpropanolamine, ephedrine, and oxilofrine.[4][5]

Metaraminol was first described and introduced for medical use by 1955.[9][10]
