A fatal overdose of flurazepam was documented in a 52-year-old female with a history of depression. Toxicological analysis confirmed high flurazepam concentrations in tissues, indicating suicidal ingestion.

Area of Science:

  • Forensic Toxicology
  • Clinical Chemistry
  • Pharmacology

Background:

  • Benzodiazepine overdose cases require accurate toxicological assessment.
  • Flurazepam is a long-acting benzodiazepine used for insomnia.
  • Understanding flurazepam's toxicokinetics is crucial for interpreting postmortem findings.

Observation:

  • A fatal case involving suicidal ingestion of approximately 2.2 grams of flurazepam is presented.
  • The deceased, a 52-year-old female with a history of depression and suicide attempts, showed no significant autopsy findings.
  • Gastric contents revealed 600 mg of flurazepam, with femoral blood levels at 5.5 mg/L.

Findings:

  • Comprehensive toxicological analysis detected only flurazepam and its metabolites in biological samples.

  • High concentrations of flurazepam were measured in femoral blood (5.5 mg/L), liver (130 mg/kg), bile (33 mg/L), vitreous humor (1.3 mg/L), and urine (3.3 mg/L).
  • The active metabolite, desalkylflurazepam, was present but at significantly lower levels than the parent drug.

    • Implications:

    • This case highlights the potential lethality of massive flurazepam ingestion.
    • Accurate toxicological quantification is essential for determining cause of death in overdose cases.
    • The findings contribute to the understanding of flurazepam's distribution and metabolism in fatal poisonings.
