Lappaconite Hydrobromide (Lappaconite HBr), a kind of alkaloid isolated from Aconitum sinomontanum Nakai and has showed anti-inflammatory effects [1, 2]. Lappaconite HBr acted as an analgesic drug in China. The Aconitum sinomontanum belongs to the Ranunculaceae family and it is used widely as an antirheumatic and analgesic agent in traditional Chinese medicine [1].
In vitro: N/A
In vivo: Lappaconite Hydrobromide absorption percentage in rat stomachs after administration was 9.67%. The absorption percentages at colon, jejunum, ileum and duodenum were, 9.51%, 11.83%, 12.95%, and 19.61%, respectively. The uptake of lappaconite hydrobromide was linearly increased when the concentration was raised from 10 mg/L to 40 mg/L, whereas the absorption rate constant kept at the same level. The LD50 values are of 10.5 mg/kg (i.p. administration) and 9.9 mg/kg (i.p. administration) in mice and rat, respectively. In addition, in anesthetized rabbits injected with lappaconite up to 1 mg/kg, cardiac arrhythmia was quickly observed [3].
