药动学是研究药物在体内的动态过程，对新药筛选、剂量控制、用药安全有效等问题具有现实意义。化学药物药动学研究较多，但中药，尤其是中成药因成分复杂，对其进行药动学研究则困难较多。近几年来对中成药的药动学研究，从深度和广度上得到逐步发展，实验方法也逐步建立，就 Pharmacokinetics is the study of the dynamic process of drugs in the body, and has practical significance for the screening of new drugs, dose control, and the safe and effective use of drugs. There are many researches on the pharmacokinetics of chemical drugs, but traditional Chinese medicines, especially Chinese patent medicines, are more difficult to study pharmacokinetics because of their complex composition.
