香荷药条体内外释药相关性的研究

Studies on correlativity between in vivo and in vitro release of XIANGHE SUPPOSITORY

目的 考察香荷药条在体内外释药的相关性。方法 体外溶出方法采用电磁搅拌法 ,体内释药量采用测定给药系统体内释药后剩余药量的方法间接测定 ,采用 HPL C法以盐酸小檗碱的含量变化作为考察指标。结果 香荷药条的体内释药百分率与体外释放百分率之间存在良好的相关性。结论 香荷药条可通过控制其体外释放达到预测体内吸收的目的。

Object To study the correlativity between the in vivo release of healthy volunteers and the in vitro dissolution of XIANGHE SUPPOSITORY(XS). Methods The electromagnetic stirring method was used to determine the in vitro dissolution of XS, and the in vivo release was got by the indirect method, assaying the content of the left XS after it had released in administering system, HPLC was used for the determination of XS with the index of variant content of berberine hydrochloride. Results A good correlativity was shown between the percentage of in vivo release and in vitro dissolution of XS. Conclusion In vitro dissolution test under the given conditions could indicate the in vivo absorption of XS.
