Summary
Therapeutic drug monitoring (TDM) aids personalized epilepsy treatment, but its effectiveness depends on appropriate use and drug-specific correlations. Guidelines are presented to optimize TDM for better patient outcomes.
Area of Science:
- Pharmacology and Therapeutics
- Clinical Pharmacy
- Neurology
Context:
- Therapeutic drug monitoring (TDM) has been utilized for individualizing epilepsy treatment since the 1970s.
- Recent years have seen questioning of TDM's value due to suboptimal outcomes from inappropriate application.
- This review addresses the need for updated guidelines on TDM for antiepileptic drugs.
Purpose:
- To present and discuss guidelines for the appropriate use of TDM in epilepsy management.
- To evaluate the variable utility of TDM based on drug-specific pharmacokinetic properties and concentration-effect relationships.
- To highlight the importance of evidence-based application for optimizing TDM's role in patient care.
Summary:
- The effectiveness of TDM varies significantly among antiepileptic drugs.
- TDM is crucial for drugs like phenytoin but less valuable for others, such as vigabatrin.
- For newer antiepileptics like lamotrigine, topiramate, and gabapentin, TDM's utility is probable but requires further investigation.
- A lack of robust concentration-effect studies for novel antiepileptics hinders rational TDM implementation.
Impact:
- Provides evidence-based guidelines to improve the rational and effective use of TDM in epilepsy therapy.
- Aims to enhance patient outcomes by ensuring TDM is applied appropriately based on drug characteristics.
- Highlights research gaps in concentration-effect relationships for new antiepileptic drugs, guiding future studies.
