    Area of Science:

    • Forensic Toxicology
    • Clinical Chemistry
    • Pharmacology

    Background:

    • Verapamil is a commonly prescribed calcium channel blocker.
    • Drug-induced deaths require accurate toxicological analysis.
    • Understanding Verapamil's role in fatalities is crucial for public health.

    Purpose of the Study:

    • To report postmortem Verapamil concentrations in fatal cases.
    • To investigate the association between Verapamil levels and cause of death.
    • To analyze Verapamil in combination with other substances like alcohol.

    Main Methods:

    • Analysis of Verapamil in liver, blood, and stomach tissue samples.
    • Tissue digestion using acid or enzymatic methods (subtilisin).
    • Extraction using dichloromethane or 1-chlorobutane.
    • Quantification by gas chromatography with a nitrogen-phosphorus detector.

    Main Results:

    • Presented postmortem findings for fourteen Verapamil-related deaths.
    • Reported Verapamil concentrations in various tissues and in combination with other drugs/alcohol.
    • Discussed the toxicological significance of measured Verapamil levels.

    Conclusions:

    • Verapamil can be implicated in fatal outcomes, especially when combined with other substances.
    • Accurate postmortem quantification of Verapamil is essential for death investigation.
    • The study provides valuable data for forensic toxicologists and medical examiners.
