Pharmacokinetics can reveal the dynamic changes of drugs in vivo, obtain the basic pharmacokinetic parameters of drugs, and clarify the process and characteristics of drug absorption, distribution, metabolism and excretion. It is an important basis for animal species selection and relationship building between dose-effect and toxicity-effect, and can provide reference for designing and optimizing the administration in clinical trials.
Toxicokinetics is one of important researches of pharmacotoxicology. It mainly studies the whole body exposure degree and duration of the tested substance at different dose levels in toxicity test, so as to predict the potential risks of the tested substance when it is exposed to human body. Toxicokinetic tests are not a simple description of the basic pharmacokinetic parameters of drugs, but focus on explaining the results of toxicity test and predicting human safety.
