中药群体药代动力学专家共识(征求意见稿)

Expert consensus on population pharmacokinetics of Chinese medicine(draft version for comments)

中药群体药代动力学(population pharmacokinetics,PPK)研究以治疗窗窄的有毒中药、或目标人群极不均一的中药、或不良反应较多的中药为研究对象,选择中药中有确切治疗作用的已知成分、有毒成分、有毒代谢酶为研究指标,采用完整的PPK采样设计方法制定采样时间点和样本量。利用气相色谱法、高效液相色谱法、色谱-质谱联用法等方法检测目标成份。最终采用总量统计矩分析方法拟合各成份PPK参数,获得能体现中药整体趋势的PPK模型,为临床合理调整给药剂量提供依据。

In population pharmacokinetic （PPK） research of Chinese medicines with narrow therapeutic windows of toxicity, or when the target population is not homogeneous, or when there are frequent adverse reactions to parenterally administered Chinese medicine, select those that have a definite therapeutic effect, and in which the compositions of the toxic substances compositions are known, for study, and use complete PPK sampling design to take samples at specific time points. Use gas chromatography, HPLC, and LC-MS methods for the detection of target components. Finally, use total quantity statistical moment analysis, to account for each com- ponent of the PPK parameters. Thus, PPK model can reflect the overall trend of Chinese medicine, to provide the basis for reasonable clinical dosage adjustments.
