Sotalol hydrochloride has class II and III anti-arrhythmic properties and non selective adrenergic beta receptor blocking action.

Sotalol hydrochloride (Betacor®) has two main actions;

1-Beta-blocking action with class II antiarrhythmic property, it increases sinus cycle length (slows heart rate), decreases A V nodal conduction and increases A V nodal refractoriness.

2-Class III antiarrhythmic action; it prolongs atrial and ventricular action potentials and prolongs the atrial and ventricular refractory periods, through blocking potassium channels (phase 3).

Sotalol hydrochloride (Betacor®) is completely absorbed after oral administration and has an absolute bioavailability of 100%.Peak plasma levels occur within 2-3 hours after oral intake. Plasma protein binding is about 35%. Sotalol hydrochloride is excreted mostly unchanged in urine and the elimination half-life ranges from 7-18 hours which is increased in the elderly and in renal failure. Sotalol hydrochloride can cross the placenta and is excreted in breast milk.

May be present due to its ß-blocking action, e.g., hypotension, bradycardia and conduction disturbances in A V node.
