Amiodarone Drug Class
As part of a class of drugs called Class III antiarrhythmics, amiodarone (Cordarone®, Pacerone®, Nexterone®) can help treat serious, abnormal heartbeats called ventricular arrhythmias. This prescription medication comes as tablets or an injection that is given slowly into a vein (intravenous, or IV, infusion).
Amiodarone works by blocking potassium channels in the heart, which prevents potassium from leaving the cells of the heart muscle. This helps prolong the period of time the heart cells will respond to a new electrical signal. Thus, amiodarone helps the heart tissue resist any electrical signal that is trying to come through prematurely.
