金雀异黄素壳聚糖微球胶囊的体内药动学研究

Internal Pharmacokinetical Study on Genistein Chitosan Microsphere Capsule

目的:比较金雀异黄素壳聚糖微球胶囊(M.C)与普通胶囊(C.C)的动物体内分布情况,探讨新制剂微球胶囊是否具有缓释靶向性。方法:采用高效液相色谱法分析,3P97软件拟合,进行微球胶囊与普通胶囊的体内药动学研究。结果:微球胶囊在体内各脏器的浓度与普通胶囊相比降低较缓慢,可以在较长时间维持一定的药物浓度;金雀异黄素普通胶囊在小鼠体内分布以肝脏为主,微球胶囊在体内分布与之相比有明显改变,以肺与脾脏为主。结论:金雀异黄素聚糖微球胶囊具有较好的缓释性,并在分布上对肺脾具有较高的选择性。

Objectivre:To compare the distribution of genistein chitosan microsphere capsule (M.C) in vivo in rats with that of genistein common capsule (C.C).To research slow-released target microsphere capsule. Method: The study on pharmacokinetics of M.C and C.C were analyzed by HPLC and 3P97 software. Results : The concentrations of M. C distributed among various organs decreased slower than those of C. C and were able to keep a certain concentration for a long time.Genistein common capsule mainly distributed in livers of rats, while genistein chitosan microsphere capsule distributed mainly in lungs and spleens of rats. Conclusion: The chitosan microsphere capsule of genistein has better slow-release and has tendency to distribute in lungs and spleens.
