Tóm tắt

The present study aimed to investigate the sub-chronic toxicity of “Phong thap dan” (PTD) tablets through oral administration in experimental animal. The sub-chronic toxicity was evaluated by the WHO recommendation in Wistar rats at doses of 0.72 g/kg/day (equal to recommended human dose) and 2.16 g/kg/day (3 times as high as recommended human dose). In the sub-chronic experimental group, the PTD was administered orally daily for 8 consecutive weeks. In the evaluation of sub-chronic toxicity, there were no behavioral and physiological change or sign of toxicity. The result of the hematological and biological parameters after administration of PTD tablets showed no change. The histopathology analysis of livers and kidneys indicated that no significant difference was observed between the exposed and unexposed rat groups. In conclusion, “Phong thap dan” tablets did not produce sub-chronic toxicity in Wistar rats.
