Lesson Eight:

Mathematical Implementation of
Pharmacokinetic and Pharmacodynamic Models

Overview:

This lesson will provide an overview of how the pharmacodynamic (PD) effect is described mathematically and how it is included in a PK/PD model to relate drug concentrations to effect. The most common PD models used to describe an immediate or delayed effect of drug concentration will be discussed. Additionally, this lecture will provide a brief introduction of the concepts of allometry, physiologically-based PK (PBPK) modelling and population PK/PD modelling. 

Learning objectives:

  • Understand the Emax model

  • Describe direct PK/PD models

  • Describe turnover (indirect) PK/PD models

  • Understand the basic principles of allometry  

  • Get a basic understanding of PBPK.

  • Understand the basic principles of population PK/PD modelling
