How Sotalol works
Sotalol is both a non-selective beta blocker and a class III antiarrhythmic medicine. Initially, it acts by slowing down the heart rate and reducing the force with which the heart contracts, achieved by blocking beta receptors. This process decreases the heart's workload and its oxygen requirements. Subsequently, Sotalol prolongs the action potential duration and the effective refractory period. These actions help to regulate abnormal heart rhythms.
