  • Toxicokinetics testing


    The research purpose of toxicokinetics is to learn the systemic exposure degree and duration time of subjects in toxicity tests under different dose levels and predict the potential risk of subjects in human exposure. Toxicokinetics is one of the important research contents of non-clinical toxicity tests and the research emphasis is to explain toxicity test results and predict human safety, rather than a simple description of the basic parameters characteristics of pharmacokinetics.
