Results from this study4

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone4

In this study, Glucagon was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Glucagon.

    Summary · context
    Plasma norepinephrine and epinephrine levels were measured before and after glucagon administration in 28 patients suspected of having a pheochromocytoma: three patients were subsequently found to have tumors.

    In patients with suspected pheochromocytoma, epinephrine levels after glucagon did not distinguish patients with tumors from those without tumors.

    Summary
    Epinephrine levels doubled, on the average, in patients who did not have pheochromocytomas, and were not useful in distinguishing the patients with or without tumors.

    In patients with suspected pheochromocytoma, comparison with placebo attributed catecholamine changes to glucagon rather than injection side effects.

    Summary
    A comparison of the response to glucagon and a placebo indicated that changes in plasma catecholamine levels were hormone-related and not the result of side-effects accompanying injection.
