Гидрохлорид соталола

Описание

Sotalol is a non-selective antagonist of β-adrenergic receptors (β-ARs; IC₅₀s = 8.9 and 5.2 μM for β1- and β2-ARs, respectively) and a class III antiarrhythmic agent. It decreases delayed outward potassium currents (IK) in guinea pig ventricular cells and prolongs action potential duration in electrically stimulated isolated guinea pig papillary muscles when used at a concentration of 100 μM. Sotalol decreases heart rate and increases blood pressure and the cardiac functional refractory period (FRP) in a canine model of ventricular tachycardia induced by programmed electrical stimulation (PES). Formulations containing sotalol have been used in the treatment of ventricular arrhythmias and maintenance of normal sinus rhythm in patients with atrial fibrillation or flutter (AFIB/AFL).

Химические свойства

White Crystalline Solid

Использование

Sotalol hydrochloride is used as a potent beta adrenergic antagonist, prolongs the action potential and increases the refractory period. Sotalol hydrochloride is also considered a non-selective β blocker and a potassium channel blocker with an IC50 of 43 μM.

Определение

ChEBI: A hydrochloride salt that is the monohydrochloride of sotalol. It has both beta-adrenoreceptor blocking (Vaughan Williams Class II) and cardiac action potential duration prolongation (Vaughan Williams Class III) antiarrhythmic properties. It is used (usually as the hydrochloride salt) for the management of ventricular and supraventricular arrhythmias.

Биологическая активность

A relatively potent pure β adrenergic antagonist, unique in possessing additional class III antiarrhythmic activity. Also available as part of the Mixed Adrenergic Tocriset™ .
