This study details lamotrigine (Lamictal) detection in two cases. One case showed natural death from seizure disorder, while the other indicated lamotrigine intoxication.

Area of Science:

  • Forensic Toxicology
  • Analytical Chemistry
  • Pharmacology

Background:

  • Lamotrigine (Lamictal) is an anticonvulsant with an unestablished therapeutic range, reported between 2-14 mg/L.
  • Accurate quantification of lamotrigine is crucial for forensic and clinical toxicology.
  • Gas chromatography-nitrogen-phosphorus detection and GC-MS are key analytical methods.

Observation:

  • Lamotrigine was identified in postmortem investigations by the Office of the Chief Medical Examiner, State of Maryland.
  • Case 1: Lamotrigine (8.3 mg/L) detected with primidone and phenobarbital.
  • Case 2: High lamotrigine levels (52 mg/L blood, 41-220 mg/kg liver) found, with no other detected drugs.

Findings:

  • Gas chromatography-nitrogen-phosphorus detection and GC-MS confirmed lamotrigine presence without derivatization.

  • Case 1: Cause of death - seizure disorder (natural).
  • Case 2: Cause of death - lamotrigine intoxication (undetermined manner).

    • Implications:

    • Highlights the importance of validated analytical methods for lamotrigine in forensic cases.
    • Suggests potential for lamotrigine toxicity at concentrations significantly higher than the reported therapeutic range.
    • Underscores the need for established toxicological reference ranges for lamotrigine in postmortem analysis.
