RESUMEN
Objective: Acute and subacute toxicity analysis of AND-2-HyP-ß-CYD complex was conducted in Sprague-Dawley (SD) rats following oral and inhalation routes of administration. Methods and Results: Single dose acute toxicity was carried out at 2000 mg/kg of AND-2-HyP-ß-CYD complex, while the doses of 200, 400, and 666 mg/kg were administered, over a period of 28 days under repeated dose oral toxicity study. Hence, LD50 (lethal dose) was found to be >2000 mg/kg in addition to NOAEL (no observed adverse effect level) of 666 mg/kg. Correspondingly, single dose acute inhalation toxicity of AND-2-HyP-ß-CYD complex was carried out at 5 mg/L/4 h/day and subacute inhalation toxicity at 0.5, 1, and 1.66 mg/L/4 h/day over a period of 28 days. The NOAEL and LOAEL (lowest observed adverse effect level) were estimated to be 0.5 mg/L/4 h/day and 1 mg/L/4 h/day, respectively. Conclusion: The findings of the present study would further be useful in assessing and utilizing the medicinal and therapeutic benefits of AND-2-HyP-ß-CYD complex.
