This study quantifies clomipramine and norclomipramine in postmortem tissues. Brain levels are crucial for assessing toxicity, as liver and blood alone may be insufficient due to redistribution.

Area of Science:

  • Forensic Toxicology
  • Analytical Chemistry
  • Pharmacology

Background:

  • Tricyclic antidepressants (TCAs) like clomipramine are widely prescribed.
  • Assessing TCA toxicity in postmortem cases is challenging due to complex pharmacokinetics.
  • Limited data exists on clomipramine and norclomipramine tissue distribution and toxicity thresholds.

Observation:

  • Clomipramine and its active metabolite norclomipramine were quantified in various tissues from two postmortem cases.
  • Liquid chromatography-mass spectrometry was employed for accurate identification and quantification.
  • Brain tissue clomipramine and norclomipramine levels were determined, addressing a gap in existing literature.

Findings:

  • Postmortem redistribution of TCAs, particularly in the liver, can confound toxicity assessments.

  • Liver and blood concentrations alone may not accurately reflect overall clomipramine toxicity.
  • Brain tissue analysis provides essential data for evaluating clomipramine and norclomipramine toxicity magnitude.

    • Implications:

    • This research enhances the toxicological database for clomipramine and norclomipramine.
    • Including brain tissue analysis is vital for accurate postmortem toxicity assessment in clomipramine cases.
    • Findings support the need for comprehensive tissue analysis in complex forensic investigations involving TCAs.
