Nobody likes Amiodarone, not even the doctors who prescribe it. I recently wrote a post about it and all the side effects it can cause. A newer drug, Dronedarone, is usually recommended for younger patients. The longer you are on Amiodarone, the better the chances that the side effects will show. Dronedarone isn’t as effective as Amiodrone in controlling Atrial Fibrillation, but has less side effects.
New research released today at the ACC10 meeting in Atlanta shows that in two seperate trial studies, patients with controlled Atrial Fibrilation can safely switch from Amiodarone to Dronedarone in as little as two days. If you have a slow heart rate (Bradyarrhythmia) or a long QT interval, the 48 hour guideline probably isn’t the best therapy for you. Your own cardiologist will be your best source of information.
