Delays in PKPD
PAGE June 27, 2023, A Coruña, Spain
Modeling Delays in Pharmacokinetics and Pharmacodynamics
Mathematical and Computational Sciences Special Interest Group of International Society of Pharmacometrics will present a one day workshop on Modeling Delays in Pharmacokinetics and Pharmacodynamics using NONMEM on Tuesday the 27th of June. The course will provide an overview of biological systems exhibiting delays, concepts of lifespan driven pharmacodynamic response, modeling of cell maturation, transduction delays, and nonlinear mixed effect lifespan models. Delay differential equations (DDEs) will be introduced and implemented in NONMEM pre-release version 7.5. The course will consist of both lectures and hands-on computer exercises. Source code for DDE based PK/PD models and data will be provided to the participants. For more information contact wk@buffalo.edu.
