地锦草颗粒的急性亚急性毒性试验

Acute and Subacute Toxicity Tests of EUPHORBIA HUMIFUSA Granule

为了评价地锦草颗粒的安全性,分别选取昆明种小白鼠、Wistar大鼠进行了急性、亚急性毒性试验。急性毒性试验结果,地锦草颗粒对小鼠经口服给药LD50>5 000 mg/kg b.w.,其毒副作用很小或无毒副作用。亚急性试验结果,连续给药4周,停药后继续观察2周,试验组大鼠生理、生化及病理等各项指标均在正常范围内,与对照组无显著差异(P>0.05),停药后各组也未见药物延迟性毒性反应,表明地锦草颗粒长期用药对大鼠无明显毒性,是比较安全的制剂。
