    Patients recovering quickly from large diazepam overdoses did not rapidly eliminate the drug or its active metabolites. Full recovery likely results from tolerance to the depressant effects of diazepam.

    Area of Science:

    • Pharmacology
    • Clinical Toxicology

    Background:

    • Benzodiazepine overdose can lead to significant central nervous system depression.
    • Diazepam, a common benzodiazepine, has a long half-life and active metabolites.

    Observation:

    • Two patients ingested massive doses of diazepam (500 mg and 2,000 mg) with suicidal intent, resulting in coma.
    • Despite high concentrations of diazepam and its active metabolites (desmethyldiazepam, temazepam, oxazepam), patients recovered within 48 hours without major complications.

    Findings:

    • High levels of diazepam and its active metabolites were detected in blood samples for up to two weeks post-ingestion.
    • Clinical recovery was rapid, despite the slow elimination of these pharmacologically active compounds.

    Implications:

    • Rapid clinical improvement in diazepam overdose is not due to swift drug clearance.
    • Patient recovery may be attributed to physiological adaptation or tolerance to the depressant effects of diazepam and its metabolites.
