Research Topics

1. External evaluation of Population Pharmacokinetic-Pharmacodynamic (PK-PD) models.

2. Population Pharmacokinetic-Pharmacodynamic (PK-PD) modeling and simulation.

3. Application of Pharmacometrics (PMx) to Clinical Pharmacology and Pharmacokinetic consultation.

Our laboratory is studying the clinical application of PMx.There is a certain proportion of patients who don't receive proper treatment at the dosage described in the package insert or guideline.PMx is an excellent tool for patients who need individualized dosing regimens. The goal is to establish guidelines that enable more quantitative implementation of the optimal dose increase/decrease and dose interval setting.
