Summary

Certain drugs can trigger epileptic seizures. This review identifies medications with high, intermediate, and low epileptogenic potential, aiding in assessing drug-induced seizure risk.

Area of Science:

  • Pharmacology
  • Neurology
  • Clinical Toxicology

Background:

  • Drug-induced seizures are a significant clinical concern.
  • Establishing a causal link between drug exposure and seizures is challenging.
  • Understanding the epileptogenic potential of medications is crucial for patient safety.

Purpose of the Study:

  • To develop criteria for assessing the drug-induced seizure risk.
  • To identify drugs with varying levels of epileptogenic potential.
  • To provide a framework for evaluating drug-related epilepsy.

Main Methods:

  • Systematic review of scientific literature.
  • Analysis of case reports and clinical studies on drug-induced seizures.
  • Development of a grading system for epileptogenic potential.

Main Results:

  • Drugs like meperidine, sevoflurane, clozapine, phenothiazines, and cyclosporine exhibit high epileptogenic potential.
  • Propofol, maprotiline, tricyclic antidepressants, and chlorambucil show intermediate potential.
  • Fluorquinolones, carbapenems, bupropion, and iodinated contrast media have low potential; interferon alpha has minimal/inconclusive potential.

Conclusions:

  • Several marketed drugs possess significant epileptogenic properties.
  • A tiered classification of drug epileptogenicity aids in risk assessment.
  • Clinical vigilance is necessary when prescribing potentially epileptogenic medications.
