Gastrointestinal radiography with glucagon.

R E Miller, S M Chernish, R L Brunelle

    Gastrointestinal Radiology
    |January 30, 1979
    PubMed
    Summary

    Glucagon is effective for hypotonic diagnostic imaging, showing a rapid onset and predictable action when administered intravenously. Side effects were minimal, primarily nausea and vomiting, supporting its use in diagnostic radiography.

    Area of Science:

    • Radiology and Diagnostic Imaging
    • Pharmacology
    • Gastroenterology

    Background:

    • Diagnostic radiography utilizes various agents to enhance imaging.
    • Glucagon's potential as a smooth muscle relaxant for diagnostic purposes requires evaluation.
    • Comparison with placebo and anticholinergic drugs is essential for efficacy assessment.

    Purpose of the Study:

    • To evaluate the efficacy and safety of glucagon in diagnostic radiographic examinations.
    • To compare glucagon's effects with placebo and anticholinergic agents.
    • To determine optimal administration routes and dosages for glucagon in imaging.

    Main Methods:

    • Nine double-blind, crossover diagnostic radiographic studies were conducted.
    • Participants received glucagon intramuscularly or intravenously, compared to placebo or anticholinergic drugs.
    • Studies focused on the upper gastrointestinal tract, esophageal varices, and the colon.

    Main Results:

    • Glucagon is safely administrable via intramuscular and intravenous routes.
    • Intravenous glucagon demonstrated rapid onset and dose-dependent duration of action.
    • Reported side effects were infrequent, mainly nausea and/or vomiting.

    Conclusions:

    • Glucagon is a suitable agent for hypotonic diagnostic examinations.
    • Its predictable pharmacokinetics and safety profile make it a preferred choice.
    • Further research can optimize glucagon's role in gastrointestinal imaging.
