Background:

  • Intravenous anesthetic drugs can alter blood flow, leading to time-varying drug disposition.
  • Accurate pharmacokinetic models are essential for predicting drug behavior in the body.
  • Existing modeling approaches may not fully capture dynamic physiological changes.

Purpose of the Study:

  • To develop a flexible software platform for simulating time-varying physiological pharmacokinetic models.
  • To create a user-friendly tool for researchers studying drug disposition.
  • To leverage MATLAB's capabilities for advanced pharmacokinetic modeling.

Main Methods:

  • Development of a platform using MATLAB, a commercial programming software.
  • Implementation of a library of modular pharmacokinetic blocks representing physiological structures.
