    Area of Science:

    • Cardiology
    • Toxicology
    • Pharmacology

    Background:

    • Propranolol overdose can cause severe cardiotoxicity, including inotropic and chronotropic effects.
    • Standard treatments like parasympatholytics and catecholamines may be ineffective in severe cases.

    Observation:

    • A patient presented with profound inotropic and moderate chronotropic cardiotoxicity following a large propranolol overdose.
    • The patient developed sudden shock despite appearing deceptively well.

    Findings:

    • Cardiotoxicity and shock did not respond to parasympatholytics or catecholamines.
    • Glucagon administration led to the reversal of cardiotoxicity and shock.

    Implications:

    • Glucagon may be an effective treatment for severe propranolol-induced cardiotoxicity.
    • This case highlights the potential benefit of glucagon in managing propranolol overdose complications.
