[The experimental anti-arrhythmia properties of the histamine H1 receptor blockader fencarol].

Phencarol, a blocker of H1-histamine receptors, is used as an antihistaminic agent. The antiarrhythmic effect of phencarol was detected and studied on experimental models of arrhythmias in non-anesthetized rabbits in a dose of 5 mg/kg intravenously. The drug was shown to possess the pronounced antiarrhythmic and protective properties on the models of calcium-chloride-, adrenaline- and strophanthine-induced arrhythmias and to exert no influence on aconitine-induced arrhythmia. Phencarol was demonstrated to have no cardiodepressive effect.
