ObJective: To study the drug release characteristics of Shuanghuanglian in-situ gel in vitro. Method: The phosphate buffer of pH 7.4 was taken as the releasing mediator
the content of the chlorogenic acid
baicalin and phillyrin in the releasing mediator was determined by HPLC
the drug release charactersitics of the Shuanghuanglian in-situ gel was studied by Franz diffusion cell method. Result: The releasing curve of the the chlorogenic acid
baicalin and phillyrin followed the Ritger-Peppas equation kinetics
but the releasing rate of the chlorogenic acid was faster than that of the baicalin and phillyrin. Conclusion: the drug release mechanism of Shuanghuanglian in-situ was non-fickian diffusion release.
