BACKGROUND & OBJECTIVE: PartySmart is a herbal preparation intended for the management of alcohol hangover and other related toxic effects in clinical situation. The present study was designed to investigate the pharmacodynamics and oral toxicity of PartySmart, a herbal formulation in rats.
Effect of PartySmart on blood acetaldehyde and alcohol levels was evaluated at doses of 125, 250 and 500 mg/kg b.wt. in rats. Acute toxicity study was conducted with PartySmart at a limit test dose of 2000 mg/kg b.wt., p.o. In repeated dose 90 day study, PartySmart was administered at doses of 500 and 1000 mg/kg b.wt. once-a-day, orally throughout the study period.
PartySmart dose-dependently decreased blood ethanol and acetaldehyde levels as compared to control. PartySmart at a dose of 500 mg/kg b.wt. significantly reduced the area under curve (AUC) of ethanol and acetaldehyde levels. It increased the hepatic alcohol dehydrogenase (ADH) at 500 mg/kg b.wt. and aldehyde dehydrogenase (ALDH) activities at doses of 250 and 500 mg/kg b.w. significantly. Acute toxicity study showed no clinical signs and pre-terminal deaths. The LD(50) of PartySmart was found to be greater than 2000 mg/kg b.wt. No significant differences in PartySmart-treated groups were observed on body weight, food intake, haematological and clinical chemistry, and organ weight ratios as compared to control group in the repeated dose study. Histopathological examination of all target organs showed no evidence of lesions attributing to drug toxicity.
INTERPRETATION & CONCLUSION: PartySmart enhanced acetaldehyde metabolism by increasing ADH and ALDH activity without any side effects. These findings indicate that PartySmart may exert beneficial role in the management of alcohol hangover without any toxicity.
PartySmart是一种草药制剂,旨在临床环境中用于管理酒精宿醉及其他相关毒性作用。本研究旨在调查一种草药配方PartySmart在大鼠体内的药效学和口服毒性。
以125、250和500mg/kg体重的剂量评估PartySmart对大鼠血液中乙醛和酒精水平的影响。采用极限试验剂量2000mg/kg体重经口对PartySmart进行急性毒性研究。在重复给药90天的研究中,整个研究期间每天一次经口给予PartySmart,剂量为500和1000mg/kg体重。
与对照组相比,PartySmart剂量依赖性地降低了血液中的乙醇和乙醛水平。500mg/kg体重剂量的PartySmart显著降低了乙醇和乙醛水平的曲线下面积(AUC)。它在500mg/kg体重时增加了肝脏乙醇脱氢酶(ADH)活性,在250和500mg/kg体重剂量时显著增加了乙醛脱氢酶(ALDH)活性。急性毒性研究未显示临床症状和濒死前死亡。发现PartySmart的半数致死量(LD50)大于2000mg/kg体重。在重复给药研究中,与对照组相比,PartySmart处理组在体重、食物摄入量、血液学和临床化学指标以及器官重量比方面未观察到显著差异。对所有靶器官的组织病理学检查未发现归因于药物毒性的病变证据。
PartySmart通过增加ADH和ALDH活性增强乙醛代谢,且无任何副作用。这些发现表明PartySmart可能在酒精宿醉管理中发挥有益作用且无任何毒性。
