摘要
采用溶剂挥发法制备了尼索地平微球 ,考察了制备工艺中影响微球质量的 5个主要因素 ,筛选出较理想的处方和工艺。所得微球形态圆整 ,表面光滑 ,粒径 (18.2± 3.8) μm,载药量 2 1.2 % ,包封率 85 .4 %。
The PLGA microspheres loading nisoldipine were prepared by the solvent evaporation method. Several influential variables had been studied and the satisfactory formulation was selected. The nisoldipine microspheres were smooth spheres observed by scanning electron microscope. The mean diameter was (18.2±3.8)μm, the drug-loading ratio was 21.2% and the entrapment efficiency was 85.4%.
