【摘要】 目的测定环维黄杨星D透皮贴剂在新西兰兔体内环维黄杨星D的药-时曲线,并与静脉注射和口服给药相比较,计算其体内药动学参数和生物利用度。方法采用柱前衍生化RP-HPLC法,测定给药后不同时间段兔体内血浆中环维黄杨星D的含量,用3p87药动学软件进行药动学参数模拟。结果经皮给药的血药浓度明显较口服平稳,达峰时间推后,持效时间延长,贴剂中环维黄杨星D的绝对生物利用度为30.465%。结论环维黄杨星D透皮贴剂具有明显控释特征,可较长时间维持稳定有效的血药浓度。更多还原

【Abstract】 Objective To evaluate the pharmacokinetic parameters and bioavailability of Cyclobuxine D in transdermal patch in Newzealand rabbits by determining concentration-time curve and by comparing with the pharmacokinetics of Cyclobuxine Dinjection and suspension.Methods Precolumn derivatization RP-HPLC was used to detect the concentration of Clovirobuxine D in rabbits plasma at different time,and software 3p87 was used to analyze the pharmacokinetics parameter.Results In contrast to oral delivery,relatively steadily sustained blood concentration with minimal fluctuation and prolonged peak time were presented in the rabbits over a long period after transdermal administration.The absolute bioavailability of Cyclobuxine D was 30.472 %.Conclusion Cyclobuxine D Patch exhibits good controlled-release properties and maintains appropriate blood concentration for a prolonged time.更多还原
