The “Key Technology Platform for Pharmacokinetic Research” is a joint initiative established by Lewwin Pharm and the Drug Metabolism Research Center of Jilin University (one of the earliest research institutes in China to utilize LC-MS/MS for pharmacokinetic studies). Professor Jingkai Gu, Director of the Center, is a Tang Aoqing Distinguished Professor at Jilin University and an expert in the field of pharmacokinetics. This collaboration brings together the strengths of both parties to provide one-stop services for the development, validation, and application of pharmacokinetic methods for both small and large molecule drugs.
