What is Bretylium?

Plain description, key identifiers and synonyms

Bretylium is a quaternary ammonium cation having 2-bromobenzyl, ethyl and two methyl groups attached to the nitrogen. It blocks noradrenaline release from the peripheral sympathetic nervous system, and is used in emergency medicine, cardiology, and other specialties for the acute management of ventricular tachycardia and ventricular fibrillation. It has a role as an antihypertensive agent, an adrenergic antagonist and an anti-arrhythmia drug.
