药代动力学英文 Pharmacokinetics (PK) is the study of the time course and effects of drugs, including their absorption, distribution, metabolism and excretion from the body. It focuses on how drugs are absorbed into the body, how they are distributed throughout the body, how they are metabolized and inactivated, and how they are excreted from the body, as well as their associated adverse effects. PK studies aim to understand how a drug works, and how it can be used most effectively for therapeutic purposes. This includes understanding the pharmacokinetic properties of a drug, such as its absorption, distribution, metabolism and excretion. Additionally, PK studies aim to identify the key factors that affect drug absorption, distribution, metabolism and excretion, such as drug solubility, metabolism and tissue distribution. Finally, PK studies investigate how a drug interacts with other drugs, and how it interacts with the body's metabolism, both after administration and during its elimination phase. 本文来源：https://www.wddqw.com/doc/c501fd932fc58bd63186bceb19e8b8f67c1cefee.html
