In Vivo PK

       The rat PK experiment is a commonly used method in PK research, which can help us understand the absorption, distribution, metabolism, and excretion processes of drugs in rats. In this experiment, researchers will inject or orally administer drugs to rats, and then collect blood or tissue samples at different time points to measure drug concentrations. By analyzing the changes in drug concentration over time, researchers can calculate the absorption rate, bioavailability, half-life and other important parameters of the drug, providing important basis for drug development.
