The antiarrhythmic action of the newly developed compound 44Bu (an original compound that was synthesized at our Faculty of Pharmacy) was tested on a model of aconitine-induced arrhythmia and compared with the effect of lidocaine. Both tested substances were administered either as therapeutic or prophylactic agents. 44Bu was highly effective in reducing the occurrence of ventricular fibrillation from 94% to 8% by therapeutic administration, and to 0% by prophylactic administration. The overall mortality rate was significantly reduced by 44Bu from 100% to 25% in the case of therapeutic administration, and to 0% in the case of prophylactic administration. In contrast, there was not any significant difference between therapeutic and prophylactic administration of lidocaine. The occurrence of ventricular fibrillation dropped from 94% to 50% with therapeutic administration, and to 67% with prophylactic administration of lidocaine. The overall mortality rate was significantly reduced from 100% to 63% and to 67%, respectively. We conclude that the 44Bu compound is a highly effective agent in suppressing aconitine-induced arrhythmias. The antiarrhythmic effect of 44Bu was significantly more evident in comparison with lidocaine, particularly in the case of its prophylactic administration.
