The antiarrhythmic activity of the compound N-(trans-3-hydroxy-1,2,3,4-tetrahydro-2-naphthyl)-N-(3-oxo-3-phenyl-2-methylpropyl)-piperazine hydrochloride, referred to as P11, is studied on anaesthesized cats and Wistar albino rats, as well as on non-anaesthesized rabbits. Four types of experimental arrhythmia are used--with BaCl2, with chloroform-adrenaline, with strophantine G and with aconitine. The compound P11 is introduced in doses of 0.25 and 0.50 mg/kg intravenously and 10 mg/kg orally. The compound manifests antiarrhythmic activity in all models of experimental arrhythmia used, causing greatest inhibition on the arrhythmia induced by chloroform-adrenaline (in 90 per cent) and with BaCl2 (in 84 per cent). The results obtained are associated with the beta-adrenoblocking and with the membrane-stabilizing action of the compound.

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.
