Theophylline poisoning

Y Vaucher, E S Lightner, P D Walson

    The Journal of Pediatrics
    |May 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Theophylline poisoning in children can occur from medication errors. Severe toxicity may be linked to hyperglycemia and ketoacidosis, but the drug still clears predictably.

    Area of Science:

    • Pediatric toxicology
    • Pharmacokinetics
    • Clinical chemistry

    Background:

    • Theophylline is a common medication for pediatric respiratory conditions.
    • Accidental overdoses can lead to severe toxicity.
    • Understanding the drug's elimination is crucial for management.

    Observation:

    • Three cases of theophylline poisoning in young children are reported.
    • Two poisonings resulted from incorrect administration of common pediatric drugs.
    • Associated metabolic disturbances like hyperglycemia and ketoacidosis were noted.

    Findings:

    • Severe theophylline toxicity may be associated with hyperglycemia and ketoacidosis.
    • Serum theophylline levels and half-life were monitored in two patients.

  • Drug elimination followed first-order kinetics despite extremely high levels, with half-lives of 8.5 and 9.0 hours.

    • Implications:

    • Highlights the risk of medication errors in pediatric theophylline use.
    • Suggests a potential link between theophylline toxicity and metabolic derangements.
    • Confirms predictable drug elimination kinetics even in severe poisoning cases, aiding treatment strategies.
