Sotalol hydrochloride is a potent and non-selective antagonist of β-adrenergic receptor. Sotalol is also an inhibitor of potassinm channels with the IC50 value of ~1.2mM in HEK cell lines [1].
As a class III antiarrhythmic drug, Sotalol hydrochloride has been reported to increase the functional refractory period without reducing conduction velocity, using an in vitro experimental rabbit heart model of reentrant tachycardia. In vivo, Sotalol hydrochloride has shown to lengthen atrial and ventricular monophasic action potential duration in the intact dog heart during constant atrial pacing [2].Besides, Sotalol is a β-adrenergic receptor blocker commonly used in rhythm-control treatment of AF (Atrial fibrillation) [3].
