Sotalol non-selectively binds to both β1- and β2-adrenergic receptors preventing activation of the receptors by their stimulatory ligand (catecholamines). Without the binding of this ligand to the receptor, the G-protein complex associated with the receptor cannot activate production of cyclic AMP, which is responsible for turning on calcium inflow channels. A decrease in activation of calcium channels will therefore result in a decrease in intracellular calcium. In heart cells, calciu… WebNov 1, 2015 · Class III antiarrhythmics (amiodarone, sotalol, or dofetilide) are effective, but have potential adverse effects and should be administered in consultation with a cardiologist. ... prolongs action ...
