摘要
目的:制备金银花肠溶片,并建立体外释放度分析方法。方法:采用湿法制粒制备片芯,以欧巴代OY-P-7171为包衣材料,并采用HPLC考察其体外释放影响因素。结果:制备金银花片芯的关键在于粘合剂的种类,而包衣膜厚度是影响药物释放的关键因素。结论:制备的金银花肠衣片在胃液中几乎不释放,在肠液中迅速释放。
Objective: Flos Lonicerae enteric - coated tablets was developed, and the method of drug release was established. Methods: Flos Lonicerae tablets was developed using wet granulation and Opaday OY- P- 7171 as coating materials. The behavior of enteric coated tablets has been evaluated in vitro by dissolution tests and determined by HPLC. Results: Two parameters were critical in preparation of the tablet: the sorts of moistening agent and the amount of dilunts. The coat weight was the significant factor of drug release. Conclusion: Flos Lonicerae enteric - coated tablets prepared did not release chorogenic acid in 0. 1 mol. L-1 HC1 solution, but release chorogenic acid rapidly in pH 6.8 phosphate buffer.
