Propafenone overdose can cause severe symptoms like coma, seizures, and heart problems. This case highlights the critical management needed for such rare but dangerous antiarrhythmic drug toxicity.

Area of Science:

  • Cardiology
  • Clinical Pharmacology
  • Toxicology

Background:

  • Propafenone is a Class IC antiarrhythmic agent.
  • Its use is infrequent, and overdose data is limited.
  • Understanding propafenone toxicity is crucial for emergency management.

Observation:

  • A patient presented with overdose of propafenone.
  • Clinical manifestations included coma, seizures, bradycardia, hypotension, and conduction delays.
  • This case represents a severe presentation of propafenone toxicity.

Findings:

  • The patient's symptoms were consistent with propafenone's known cardiac electrophysiology effects.
  • Management strategies were guided by the drug's pharmacology.
  • This case adds to the scarce literature on propafenone overdose.

Implications:

  • Clinicians should be aware of propafenone's potential for severe toxicity.
  • Prompt recognition and management are vital for patient outcomes.
  • Further research into propafenone overdose is warranted.
