In Vivo Pharmacokinetics Services

In vivo pharmacokinetics is mainly used to study the preclinical pharmacokinetics of drugs in experimental animals. Our company has extensive expertise in pharmacokinetics and can provide efficient methods to accelerate your rare disease therapy development. We can provide a one-stop, personalized, and customized service according to your specific needs.

Introduction to In Vivo Pharmacokinetics

Pharmacokinetics (PK) is dedicated to determining the absorption mechanism, biological distribution, and elimination of the drug from the body. After entering the body, drugs are absorbed into the bloodstream and transported across through biological membranes to target tissues to bind to receptors and produce a pharmacological effect. Once the effect has ended, the drug must be eliminated from the body. In vivo pharmacokinetic studies provide necessary and useful information for this, such as steady-state distribution, clearance, half-life, AUC, bioavailability, and tissue distribution, etc., to help understand the efficacy or toxicity of the drug in the body and provide more opportunities to discover more biologically and safer therapeutic drugs.
