Mechanism of action

Amiodarone is a Class III antiarrhythmic agent with properties of all four Vaughan-Williams classes. It prolongs the action potential duration and refractory period by blocking potassium channels, while also inhibiting sodium and calcium channels and beta-adrenergic receptors. This multi-channel blockade makes it effective for suppressing both atrial and ventricular arrhythmias.
