中文摘要
目的制备替尼泊苷磷脂复合物白蛋白纳米粒,并表征其理化性质。方法以人血清白蛋白和蛋黄卵磷脂E80为辅料,替尼泊苷为主药,采用超声法制备替尼泊苷磷脂复合物白蛋白纳米粒及其冻干制剂。以粒径和多分散系数(PDI)为主要考察指标来优化纳米粒的处方及制备工艺;用激光粒度分析仪和透射电镜对其形态和结构进行表征;用葡聚糖凝胶柱法测定纳米粒的包封率和载药量。结果成功制备了替尼泊苷磷脂复合物白蛋白纳米粒,平均粒径为182.3±11.7 nm,PDI为0.168±0.02,Zeta电位为-10.75±1.42 m V,包封率为82.27%±2.74%,载药量为4.29%±0.11%;冻干制剂的外观良好,复溶后的粒径和PDI均符合要求。结论所用方法简单新颖,具有较好的应用前景。
