Pharmacodynamics & toxicological profile of PartySmart, a herbal preparation for alcohol hangover in Wistar rats.

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. METHODS 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. RESULTS 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.
