Dose response to intramuscular glucagon during hypotonic radiography.
In a study to determine a dose response to glucagon during hypotonic duodenography, 15 male and female volunteers received placebo and 0.25 mg 1 mg and 2 mg glucagon intramuscularly, double-blind and cross-over. When 0.25 mg glucagon was given, the onset of drug effect was approximately 13--18 min: the mean duration of moderate hypotonicity was approximately 4--7 min. The larger the dose, the greater the duration of drug action. When 2 mg glucagon was given, the onset of drug effect occurred in approximately 4--7 min; the mean duration of moderate hypotonicity was 22--32 min. There were no changes in pulse or blood pressure attributable to the drug with these doses, and reports of nausea and diarrhea did not increase significantly until a dose above 1 mg was given. One mg glucagon given IM is useful in hypotonic upper Gl radiographic examinations. The onset of hypotonicity was 8--10 min with a duration of 12--27 min when this dose was given. Few reports of side effects were attributable to this dose.
