A Greeting from the Professor

In Department of Pharmacokinetics, we are specializing in clinical pharmacology, clinical pharmacokinetics, pharmacogenomics and analytical chemistry. We provide quality drug analysis services, analytical support and therapeutic drug monitoring (TDM) for clinician. Therapeutic drug monitoring (TDM) is a part of personalized (precision) medicine, and is defined as the management of a patient’s drug regime based on serum, plasma, or whole blood concentration of a drug. TDM is essential in order to achieve maximum efficacy of the drug as well as to avoid drug toxicity. We excel at developing new analysis method based on high-performance liquid chromatography to determine drug concentrations in blood. Clinically useful TDM does require that there is a good relationship between plasma concentration and clinical effect. We determine therapeutic target ranges indicating exposure-response (efficacy/toxicity) relationships.
Pharmacogenomics is also a part of precision medicine, which aims to tailor medical treatment to each person or to a group of people. Dose adjustment based on pharmacogenomics can improve efficacy and minimize side effects of drug treatments, resulting in better clinical outcomes and patient experiences. We determine the relationships between drug plasma concentration and drug single-nucleotide polymorphisms (SNPs) in drug metabolizing enzymes or transporters. The SNP-based approach and TDM in clinic make us confident of achieving one of our goals.
