| 摘要: |
| 目的 制备具有较高水溶性的间尼索地平微丸。方法 以磺丁醚-β-环糊精(SBE-β-CD)为成丸辅料，羟丙基纤维素乙醇溶液为黏合剂，采用挤出滚圆法制备间尼索地平微丸，对影响成球的关键参数挤出速度、滚圆转速进行筛选优化，对微丸体外释放进行评价，并对微丸进行粉体学性质的考察。结果 制得的间尼索地平微丸水中溶出度高，圆整度好，收率可达70%，各项粉体学性质较为理想。结论 以SBE-β-CD为成丸辅料，采用挤出滚圆法制备高水溶性的间尼索地平微丸在工艺上是可行的，对难溶性药物微丸的制备具有一定借鉴作用。 |

| Abstract: |
| OBJECTIVE To prepare high solubility m-nisoldipine pellets. METHODS The m-nisoldipine-sulfobutyl ether (SBE)-β-cyclodextrins (CD) pellets were prepared by extrusion-spheronization, ethanol solvent with hydroxypropyl cellulose as a binder. The effects of key parameters on spheronization process were the proportion of extrusion speed and spheronisation speed, which were investigated to obtain optimal formulation. In vitro release of pellets and micromeritics of pellets were evaluated. RESULTS m-Nisoldipine pellets have good water soluble property, presented perfect sphericity and yield over 70%. CONCLUSION The m-nisoldipine-SBE-β-CD pellets are successfully prepared by extrusion-spheronization. It presents a method for poor water soluble drugs pellets. |
