Abstract: 目的:评价脂质体鬼臼毒素外用的安全性.方法:观察组大鼠涂抹脂质体鬼臼毒素混悬液(载药量0.5%),对照组大鼠涂抹0.5%鬼臼毒素酊剂.涂药后1、2、4、6、8、10、12和24 h心脏采血,用荧光光度法测定不同时间血中鬼臼毒素浓度.2周后心脏取血测肝肾功能指标.结果:对照组浓度曲线下面积是观察组的2.3倍.观察组鬼臼毒素的峰值浓度[(166.39±14.63)ng/mL],与对照组[(378.60±26.11)ng/mL],相比有显著性差异(P<0.001).观察组大鼠的肝肾功能与对照组及空白相比组相比差异均无显著性(P>0.05).结论:脂质体鬼臼毒素混悬液外用后,全身吸收明显低于外用鬼臼毒素酊剂,并且对肝肾功能没有影响.表明脂质体鬼臼毒素外用后能降低全身毒副作用.
