Abstract:
OBJECTIVETo prepare the new traditional Chinese medicine preparation--pH-dependent brevisapin colon-specific tablets, and investigate its in vitro release, in order to discuss the feasibility of preparing colon-targeted traditional Chinese medicines.
METHODWith scutellarin, the active ingredient in brevisapin, as the evaluation index, coating prescriptions of the preparation was screened. The in vitro release determination method was adopted to detect the in vitro release performance of the preparation.
RESULTThe in vitro release determination results showed no brevisapin in artificial pH 1. 2 dilute hydrochloric acid solution for 2 h, an accumulated dissolution rate of less than 5% in pH 6. 8 phosphate buffer solution for 4 h, but an accumulated dissolution rate exceeding 90% in pH 7. 6 phosphate buffer solution for 1 h.
CONCLUSIONBrevisapin colon-specific tablets prepared can realize colon-specific release.
