生物活性
描述 Bretylium tosylate is an inhibitor of the presynaptic release of vasoconstrictor neurotransmitters. It is the sympathetic nerve and adrenergic ganglion blocking agent[3]. Bretylium reduced the velocity of hydrolysis of ACh by erythrocyte ghosts. This inhibition was competitive and the Ki of bretylium was 0.053 mM[4]. Clinical studies have shown parenteral bretylium to be effective in suppressing ventricular arrhythmias, particularly recurrent, drug resistant ventricular tachycardia or ventricular fibrillation[5].
