芍药苷胃漂浮片的制备

目的 制备芍药苷胃漂浮片,优选芍药苷胃漂浮片的制备工艺。方法 采用湿法制粒压片制备芍药苷胃漂浮片,以漂浮性能和体外累积释放率为考查指标,采用单因素筛选及正交设计法,优化芍药苷胃漂浮片处方。结果 以HPMC K4M(20%)为骨架材料、NaHCO₃(15%)为起泡剂、PVPP(7%)为释放促进剂、乳糖200为填充剂制得的胃漂浮片能立即起漂,持续漂浮12 h以上,累积释放率达90%以上。结论 优选的芍药苷胃漂浮片达到了持续漂浮及缓慢释放的要求,可操作性强。

Preparation of paeoniflorin gastric floating tablets

Objective To prepare paeoniflorin gastric floating tablets and to optimize the formulation. Methods Gastric floating tablets were prepared by wet granulation, with floating performance and in vitro cumulative release rate as evaluat indicators, single factor tests and orthogonal design test were adopted for the optimal formulation. Results With HPMC K4M 20% as reinforcing materials, NaHCO₃ 15% as gas agent, PVPP 7% as the release of accelerator, lactose as a filler, the obtained gastric floating tablet can immediately play bleaching, continued to float more than 12 hours, and the cumulative release rate was more than 90%. Conclusion The optimal formulation of paeconiflorin floating tablet has achieved a sustained and slow release request floating, the operability is good.
