Pharmacokinetics is an important part of the research on druggability of innovative drugs. The absorption, distribution, metabolism, and excretion of drugs are closely related to drug efficacy and safety. We have laboratories that meet international standards, a variety of advanced in vivo and in vitro experimental techniques and biological analysis devices. With years of experience in pharmacokinetic studies in multiple therapeutic areas or drug targets, the team leader and core R&D staff can provide a holistic approach and complete set of R&D services from early in vitro absorption, distribution, metabolism and excretion (ADME) screening to in vivo pharmacokinetic evaluation (PK) in experimental animals. Our goal is to provide fast, effective and high quality research solutions to meet the needs of the customers in ADME studies, and help customers reduce R&D costs and increase the success rate of new drug development according to their project requirements.
