商品名：Cordarone
Antiarrhythmic drug, Class III. Antiarrhythmic effects are primarily caused by blocking the outward potassium channel in cardiac tissues. Amiodarone prolongs the action potential, delays myocardial repolarization, and delays the refractory period in cardiac tissues. It also may have some alpha-adrenergic receptor, beta-adrenergic receptor, and calcium-channel blocking properties. Half-life is several days in duration, and in some animals the half-life may be as long as 100 days with chronic therapy. In horses the terminal half-life was 38-84 hours. The intravenous formulation of amiodarone use
Amiodarone is used to treat refractory ventricular arrhythmias. It is reserved for treating life-threatening arrhythmias that have been refractory to other treatments. It has been used as a last resort for recurrent hemodynamically unstable ventricular tachycardia. In horses, IV amidarone has been used to treat atrial fibrillation.
