This document discusses using pharmacokinetic, pharmacodynamic, and pharmacogenetic software for modeling and therapeutic drug monitoring. It specifically mentions the software CMwPharm++/dsim++ which enables demonstrating the behavior of drugs in the human organism. The aim of the study was to process a tolbutamide case study with the software and demonstrate the option to use the software for modeling case studies. The visual modeling approach of Edsimxx greatly simplifies the development of complex models which are easily transferrable to MwPharmxx.
