【摘要】:目的考察多西他赛囊袋张力环加速释放度试验条件,并优化多西他赛囊袋张力环的处方工艺。方法通过考察释放介质中乙醇含量(0%、5%、10%)和不同温度(37和45℃)对多西他赛囊袋张力环释药速度的影响,建立制剂体外加速释放度试验条件。利用加速释放度试验方法考察多西他赛囊袋张力环的体外释放度,筛选最优处方。结果在介质为含5%乙醇pH 7.4磷酸盐缓冲溶液、温度为(45±0.5)℃的加速释放条件下,药物释放速度提高了4倍,加速释放度与长期释放度用二项式拟合最好(y=0.004 6x~2+0.437 4x+9.683 7,r~2=0.998 4);载药量为30%,载体为PLGA5050(60K-100K=1∶1,W/W)的处方释药平稳,可持续释药30 d,符合Peppas equation释药模型。结论多西他赛囊袋张力环的释药特性可用加速释放度试验快速考察,该制剂体外释药平稳缓慢,具有临床应用前景。
