Tutorials

Introduction to PBPK modeling with PK-Sim®

This introduction video describes the very basic steps required to build a PBPK model with PK-Sim® using Morphine as an example.

PBPK model building

This tutorial demonstrates how to build a simple PBPK model of ciprofloxacin. Learn how to optimize parameters based on observed PK and mass balance information following intravenous and oral administration.

Comparing simulations and building blocks in PK-Sim® and MoBi®

This tutorial presents how to compare two simulations of the same molecule with respect to their input parameter values and quickly determine differences. Also learn how to determine which simulation parameter values may differ from the original building block used to create the simulation.

Age-dependence of PK

Using morphine as an example, learn how to build pediatric PBPK models. Starting with optimization of an adult PBPK model for morphine, learn to build individual children and populations of children and compare their PK results to adults.

How to Build a PBPK/PD Model

This tutorial introduces the fundamental concepts of PBPK/PD modeling with a special focus on practical implementation in a typical PBPK model building workflow.

Favorites in PK-Sim® and MoBi®

Spending too much time trying to locate a specific parameter? Favorites is a powerful feature to help you be more efficient. This tutorial teaches you all you need to know about them.

Model drug-drug interaction in PK-Sim®

This tutorial presents a step-by- step guide on how to setup a fully mechanistic drug-drug interaction model in PK-Sim®.

Customizing chart settings in PK-Sim® and MoBi®
