Abstract
目的 采用星点设计-效应面法优化传明酸传递体的处方.方法 逆向旋蒸法制备传明酸传递体;通过考察膜材比、脂药比及脱氧胆酸钠用量对包封率、载药量的影响,并对结果进行二项式方程拟合,用效应面法预测最佳处方,并对其稳定性进行研究.结果 确定最优处方为膜材比2∶1、脂药比6∶1、脱氧胆酸钠用量为20 mg;以该处方制备所得传明酸传递体的包封率为(81.28±1.06)%、载药量为(4.67±0.28)%、平均粒径为(105.3±7.2) nm、Zeta电位为(-38.5±2.3)mV,且实测值与预测值的偏差较小.结论 星点设计-效应面优化法筛选传明酸传递体是一种简便、可行的实验设计方法.
