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

ABSTRACT

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.
