Target concentration intervention (TCI) offers a rational approach to individual dosing by integrating pharmacokinetic and pharmacodynamic principles. This strategy moves beyond traditional therapeutic drug monitoring (TDM) and its limitations for improved patient outcomes.

Area of Science:

  • Pharmacology
  • Clinical Pharmacy
  • Drug Dosing Strategies

Background:

  • Traditional therapeutic drug monitoring (TDM) relies on a 'therapeutic range,' which may oversimplify pharmacodynamic models.
  • This oversimplification can limit the interpretation of measured drug concentrations and reduce clinical benefits for patients.

Purpose of the Study:

  • To propose Target Concentration Intervention (TCI) as a superior conceptual strategy to TDM.
  • To highlight TCI's ability to enhance rational individual dose decisions.

Main Methods:

  • Conceptual framework development comparing TCI and TDM.
  • Integration of pharmacokinetic and pharmacodynamic principles within the TCI model.

Main Results:

  • TCI utilizes a target effect and associated target concentration for dose optimization.
  • This approach offers a more rational basis for individualizing drug dosage compared to TDM.

    • Conclusions:

    • Target Concentration Intervention (TCI) provides a more robust framework for drug dosing than traditional TDM.
    • TCI's integration of PK/PD principles facilitates rational, individualized dose adjustments for improved patient care.
