This study introduces optimal control theory for calculating drug administration schedules. It ensures therapeutic drug levels are reached fastest, avoiding toxicity and sub-efficacy, particularly for intravenous infusions.

Area of Science:

  • Pharmacokinetics
  • Optimal Control Theory
  • Drug Dosing

Background:

  • Clinical pharmacokinetics involves calculating drug dosage regimens to maintain therapeutic drug levels.
  • Current methods often focus on determining drug amounts for a fixed schedule.
  • Maintaining drug concentrations between efficacy and toxicity thresholds is crucial.

Purpose of the Study:

  • To present methods for determining optimal drug administration time schedules.
  • To ensure the fastest transition to therapeutic drug levels using optimal control theory.
  • To address the challenge of optimizing drug infusion timing.

Main Methods:

  • Application of optimal control theory to determine switching times between minimal and maximal infusion rates.
  • Development of the approach for drugs administered via intravenous infusion.
