| 摘 要： | 目的:将脂质体与壳聚糖微球两种载体结合,研究一种新的载脂质体壳聚糖微球口服缓释给药系统。方法:以阿魏酸为模型药物,醋酸钙梯度法制备脂质体后与壳聚糖溶液混合,离子凝聚法制备微球,分别对脂质体和微球进行表征,研究其体外释放性质。结果:脂质体的平均包封率为(79.97±0.54)%,平均粒径为(187.6±11.9)nm,Zeta电位为-12.67±1.78,4 h释药80%。再制备成壳聚糖微球后,药物以无定型态包于脂质体中,再完整地分散于壳聚糖微球中,平均包封率为(57.89±1.72)%,平均粒径为(1.17±0.15)mm。12 h时,脂质体自微球中释放出80.97%,药物释放出32.33%,明显低于壳聚糖微球78.98%的药物释放率。结论:载脂质体壳聚糖微球具有良好的体外缓释性能。
