[Fatal colchicine poisoning].

K Harzer

    Zeitschrift Fur Rechtsmedizin. Journal of Legal Medicine
    |January 1, 1984
    PubMed
    Summary

    Colchicine serum levels were measured post-injection in two cases. The drug remained detectable in urine up to 10 days after administration, indicating prolonged colchicine presence.

    Area of Science:

    • Pharmacology
    • Toxicology
    • Analytical Chemistry

    Context:

    • Colchicine is a potent medication with a narrow therapeutic index.
    • Understanding colchicine pharmacokinetics is crucial for clinical management and toxicity assessment.

    Purpose:

    • To quantify colchicine serum concentrations post-intravenous administration in fatal cases.
    • To investigate the duration of colchicine detectability in biological matrices.

    Summary:

    • Two cases reported high colchicine serum concentrations (170 ng/ml and 240 ng/ml) prior to death following i.v. injection.
    • Colchicine was extracted from serum using Extrelut columns and analyzed via High-Performance Liquid Chromatography (HPLC).
    • Urine analysis confirmed findings and detected colchicine up to 10 days post-injection, verified by UV-curve analysis using the stop-flow method.

    Impact:

    • Provides critical data on colchicine's terminal elimination phase.
    • Highlights the importance of extended monitoring for colchicine exposure.
    • Informs clinical toxicology and forensic investigations involving colchicine.
