用途: Sotalol Hydrochloride is an adrenergic beta-antagonist that is used in the treatment of life-threatening arrhythmias.Target: Adrenergic ReceptorSotalol is a non-selective competitive β-adrenergic receptor blocker that also exhibits Class III antiarrhythmic properties by its inhibition of potassium channels. Sotalol is a competitive beta adrenoceptor antagonist devoid of membrane-stabilizing activity and intrinsic sympathomimetic activity that has no preferential actions on beta 1 or beta 2 responses. Sotalol causes concentration-dependent increases in the contractility of isolated ventricular tissue that is not blocked by previous beta or alpha blockade or catecholamine depletion. Sotalol consistently reduces the heart rate to a greater degree than propranolol and causes significantly less cardiac suppression than propranolol at a given heart rate [1]. Sotalol is not only a beta blocker but a class III antiarrhythmic drug. Its possible antifibrillatory activity was therefore investigated in both the ventricles and atria of dog heart in situ, since vulnerability to fibrillation is not the same in both these parts of the myocardium [2]. 物理化学性质: CAS号:959-24-0 常用中文名:盐酸索他洛尔 常用英文名:Sotalol hydrochloride 分子式:C12H21ClN2O3S 分子量:308.825 密度:N/A 沸点:443.3ºC at 760 mmHg 熔点:218-220°C 闪点:221.9ºC 储存条件:库房低温通风干燥 |
