As a pharmacist with expertise in pharmacology, I can confirm that amiodarone is indeed classified as an antiarrhythmic medication, but it is not a typical beta blocker. It has properties that overlap with those of a beta blocker, as it can block beta-adrenergic receptors, which is a characteristic of beta blockers. However, its primary mechanism of action is different and more complex. Amiodarone is considered a Class III antiarrhythmic agent, which exerts its effects by prolonging the action potential duration and refractory period in the heart. It also has some alpha-blocking and calcium-channel-blocking properties. read more >>

Amiodarone and beta-blockers each have been shown to reduce the incidence of sudden death in certain patient populations, share beta-blocking effects, and slow heart rate. However, it remains uncertain whether these drugs are more beneficial or harmful when used together.read more >>
