Determination of pharmacokinetics (PKs) of multicomponent pharmaceuticals and/or nutraceuticals (polypharmacokinetics, poly-PKs) is difficult due to the vast number of compounds present in natural products, their various concentrations across a wide range, complexity of their interactions, as well as their complex degradation dynamics in vivo. Metabolomics coupled with multivariate statistical tools that focus on the comprehensive analysis of small molecules in biofluids is a viable approach to address the challenges of poly-PK. This paper discusses recent advances in the characterization of poly-PK and the metabolism of multicomponent xenobiotic agents, such as compound drugs, dietary supplements, and herbal medicines, using metabolomics strategy. We propose a research framework that integrates the dynamic concentration profile of bioavailable xenobiotic molecules that result from in vivo absorption and hepatic and gut bacterial metabolism, as well as the human metabolic response profile. This framework will address the bottleneck problem in the pharmacological evaluation of multicomponent pharmaceuticals and nutraceuticals, leading to the direct elucidation of the pharmacological and molecular mechanisms of these compounds.
由于天然产物中存在大量化合物，其浓度范围广泛，相互作用复杂，以及体内复杂的降解动力学，因此确定多成分药物和/或营养保健品的药代动力学（PKs）（多药代动力学，多-PKs）是困难的。代谢组学与多变量统计工具相结合，专注于生物流体中小分子的综合分析，是解决多-PK 挑战的一种可行方法。本文讨论了使用代谢组学策略表征多药代动力学和多成分外源性药物（如复方药物、膳食补充剂和草药）代谢的最新进展。我们提出了一个研究框架，该框架整合了生物可利用的外源性分子的动态浓度谱，这些分子源自体内吸收以及肝和肠道细菌代谢，以及人类代谢反应谱。该框架将解决多成分药物和营养保健品药理学评价中的瓶颈问题，从而直接阐明这些化合物的药理学和分子机制。
