Drug clearance by diarrhea induction.

R S Porter, E B Baker

    The American Journal of Emergency Medicine
    |May 1, 1985
    PubMed
    Summary

    Gastrointestinal perfusion can effectively reduce circulating drug levels, clearing nearly 25% of phenobarbital in dogs. This method shows promise for removing ingested toxins in emergency settings.

    Area of Science:

    • Pharmacology
    • Toxicology
    • Nephrology

    Background:

    • Gastrointestinal (GI) perfusion with electrolyte solutions is an alternative to peritoneal dialysis for renal failure patients.
    • The potential for GI perfusion to influence systemic drug concentrations was previously unexplored.

    Purpose of the Study:

    • To investigate the efficacy of GI perfusion in reducing systemic levels of circulating drugs.
    • To assess the potential of GI perfusion as a method for toxin removal.

    Main Methods:

    • Nine dogs received intravenous phenobarbital and underwent GI perfusion.
    • Serum phenobarbital levels were monitored to calculate drug clearance.
    • Each dog served as its own control to minimize variability.

    Main Results:

    • Dogs undergoing GI perfusion cleared 24.8% of the initial phenobarbital dose over five hours.
    • Control dogs (no perfusion) cleared only 3.13% of the initial phenobarbital dose.
    • This indicates a significant drug removal effect attributable to GI perfusion.

    Conclusions:

    • Gastrointestinal perfusion effectively removes systemically circulating drugs like phenobarbital.
    • This procedure may offer a viable method for enhancing toxin elimination in emergency medicine.
    • Further research could explore its application in managing drug overdoses and poisonings.
