血清药理学与药代动力学整合模型的复方鳖甲软肝片日服用次数合理性研究

该课题通过体外观察大鼠含药血清对肝星状细胞(HSC-T6)增殖的影响,结合复方鳖甲软肝片中芍药苷的药物代谢动力学模型,研究复方鳖甲软肝片合理的日服用次数。大鼠每日不同次数灌胃给药,分别于给药前及第1次给药后各时间点眼眶后静脉取血,用于测定大鼠含药血清对HSC-T6增殖的影响以及大鼠血浆中芍药苷的血药浓度。综合分析时量和时效关系,制定复方鳖甲软肝片用于慢性肝炎肝纤维化的合理的日服用次数。结果表明,复方鳖甲软肝片含药血清对HSC-T6抑制的效应与芍药苷血药浓度具有良好的相关性,每日给药2次组对HSC-T6抑制的效应动力学曲线下面积(AUC)及药代动力学AUC均高于每日给药1次组和3次组。因此,复方鳖甲软肝片用于慢性肝炎肝纤维化以每日服用2次为佳。

Study on rational daily administration frequency of Fufang Biejia Ruangan tablet based on integrated serum pharmacologic and pharmacokinetic model

To observe in vitro the effect of rat drug serum on the proliferation of HSC-T6 hepatic stellate cells in the pharmacokinetic model for determining peoniflorin in Fufang Biejia Ruangan tablet, in order to discover the rational daily administration frequency of Fufang Biejia Ruangan tablet. Fufang Biejia Ruangan tablet was orally administered to rats with different daily administration frequency. Their blood was collected from veins behind eye sockets at different time points before the administration and after the first administration, in order to determine the concentration of peoniflorin in blood plasma and the effect of rat drug serums on the proliferation of HSC-T6. A comprehensive analysis was made on the relationship between pharmacodynamics and pharmacokinetics to determine the rational daily administration frequency of Fufang Biejia Ruangan tablet. The results showed a good correlation between the inhibitory effect of Fufang Biejia Ruangan tablet-contained serum on HSC-T6 and the concentration of peoniflorin in blood. The two-time administration group showed higher pharmacologic and pharmacokinetic AUCs than one-time administration and three-time administration groups. In conclusion, Fufang Biejia Ruangan table is recommended to be taken twice a day for treating liver fibrosis in chronic hepatitis.
