摘要: 目的: 探讨他汀类药物在高脂血症大鼠体内暴露水平(药代动力学参数AUC)与药效之间的关系。方法: 建立大鼠高脂血症模型,给予不同剂量的他汀类药物干预治疗,进行药代动力学和药效学测定,计算药代动力学/药效学(PK/PD)值,并进行相关分析。结果: TG-AUC在药代动力学(AUC)变化范围内(0~10.96 倍)线性关系良好,Y=0.01036X-7.6445 (γ=0.9599)。胆固醇(CHOL)-AUC、低密度脂蛋白胆固醇(LDL-C)-AUC、高密度脂蛋白胆固醇(HDL-C)-AUC由于中间数据偏低,与预测样本数据偏差太大,线性关系不明显。结论: TG-AUC在药代动力学(AUC)变化范围内(0~10.96 倍)线性关系良好,可以在知道药代动力学的相关数据基础上对药效进行预测。

Abstract: AIM: To explore the relationship between exposure level (such as pharmacokinetics parameters) and pharmacodynamics for statins in hyperlipidemia model in rats.METHODS: The hyper- lipidemia rat model was established with the method of diet-induced, and the rats were given different does of statins to treat. The pharmacokinetics and pharmacodynamics parameters were determined, and the value of PK/PD were calculated, and their correlations were analyzed.RESULTS: TG-AUC showed a good linear relationship at the range of 0-10.96 folds, Y=0.01036X-7.6445 (γ=0.9599), the intermediate data such as CHOL-AUC, LDL-C-AUC, HDL-C-AUC were on the low side, which resulted large deviation, so there was an extremely weak linear correlation in these groups.CONCLUSION: There was a good linear relationship between TG and AUC in the range of AUC (0-10.96 folds), it could be efficaciously used to predicted the pharmacodynamics upon the related datas for AUC.
