Amiodarone Hydrochloride

Overview

Basic Info

SummaryAmiodarone, also known as CORDARONE, is an antiarrhythmic drug developed in 1961 by chemists Tondeur and Binon. By 1980, it was commonly prescribed throughout Europe for the treatment of arrhythmias. In December 1985, due to the threat of a cut-off from European companies, amiodarone was approved by the FDA for the treatment of arrhythmias, even though it had not undergone rigorous randomized clinical trials. Amiodarone is considered a class III antiarrhythmic drug, but it possesses electrophysiologic characteristics of all four Vaughan Williams classes. It blocks sodium and myocardial potassium channels, contributing to slowing of conduction and prolongation of refractoriness. CORDARONE is indicated for the treatment of life-threatening ventricular fibrillation and unstable tachycardia in adults who have not responded to other antiarrhythmics.
