Cordarone Uses

How Does It Work?

Cordarone belongs to a group of medications known as antiarrhythmics. Most antiarrhythmic medications are further categorized using a system known as the Vaughn-Williams classification system. This system divides the medications into four general classes based on how they work.
 
Cordarone has properties of all four classes and, therefore, works in different ways. However, the most important way it works is by its Class III antiarrhythmic actions.
 
Class III antiarrhythmic medications block potassium channels in the heart, preventing potassium from leaving the cells of the heart muscle. This action prolongs the heart's refractory period. The refractory period is the period of time the cells of the heart muscle will not respond to a new electrical signal. By extending the refractory period, Cordarone helps the heart tissue resist any electrical signal that is trying to cause the heart to beat prematurely.
 

Alternatives to Cordarone

The antiarrhythmic class of medicines represents a large group of drugs that work in different ways to help restore and maintain the normal rhythm of the heart. These medicines are usually divided into four types, or "classes," based on the way they work in the body.
 
In general, many of the Class I and Class III antiarrhythmics can be used as alternatives to Cordarone. However, the list of actual possible alternatives for your individual situation will depend on several factors, including the type of arrhythmia being treated, the severity of the arrhythmia, and other medical conditions you may have.
