Curator's Comment: description was created based on several sources, including: https://www.ncbi.nlm.nih.gov/pubmed/6873182

Amezinium is a sympathomimetic used for its vasopressor effects in the treatment of hypotensive states. Amezinium inhibited monoamine oxidase (MAO) activity. Amezinium antagonized the response to tyramine and blocked neuronal uptake of noradrenaline. Side effects revealed are: palpitation, headache, nausea/vomiting, hot flashes, high blood pressure.

In Vitro Use Guide

Amezinium antagonized the response to tyramine and blocked neuronal uptake of noradrenaline m concentrations as low as 0.1 to 10 uM and therefore it was not surprising to find that in the presence of the lower concentration of Amezinium the effects of noradrenaline were potentiated (at the level of the ED50) by a factor of 3.5.
