Allocryptopine: A Review of Its Properties and Mechanism of Antiarrhythmic Effect

Abstract：Throughout the last decade, extensive efforts have been devoted to developing a percutaneous catheter ablation and implantable cardioverter-defibrillator technique for patients suffering from ventricular arrhythmia. Antiarrhythmic drug efficacy for preventing arrhythmias remains disappointing because of adverse cardiovascular effects. Allocryptopine is an isoquinoline alkaloid widely present in medicinal herbs. Studies have indicated that allocryptopine exhibits potential anti-arrhythmic actions in various animal models. The potential therapeutic benefit of allocryptopine in arrhythmia diseases is addressed in this study, focusing on multiple ion channel targets and reduced repolarization dispersion. The limitations of allocryptopine research are clear given a lack of parameters regarding toxicology and pharmacokinetics and clinical efficacy in patients with ventricular arrhythmias. Much remains to be revealed about the properties of allocryptopine.
