The current paper presents research results related to antiarrhythmic activity of halogen-containing derivatives of lappaconitine. Lappaconitine derivatives with iodine, chlorine or bromine substituting the anthranilate moiety at C-5` position were shown in vivo and in vitro to exhibit a more (Br, I) or less (Cl) pronounced antiarrhythmic activity in the models of calcium chloride- and adrenaline-induced arrhythmias as compared with the reference compound lappaconitine. The intensity of antiarrhythmic action depending on halogen substituent was found to be expressed by the following order: Cl < I < Br.

Keywords: Arrhythmia, lappaconitine, halogen-containing lappaconitine derivatives.
