Cordarone, which contains the active ingredient amiodarone, is used to treat a group of heart rhythm problems that can be life-threatening if left uncontrolled. Cordarone is mainly used to regulate irregular or dangerously fast heartbeats such as atrial fibrillation, atrial flutter, or unstable ventricular tachycardia.
Cordarone is sometimes used as a treatment option when other medications are ineffective or cannot be tolerated.
