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

Studies that did not test the peptide alone2

In this study, Cosyntropin 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 Cosyntropin.

    Summary
    In vivo, mean 30-min serum cortisol concentrations were 20.47 ± 2.87 and 21.62 ± 3.89 μg/dl in via plastic tube and in via direct intravenous injection tests, respectively, and did not show a significant difference (P = 0.16).

    Summary · context
    For the in vivo study, we recruited 20 healthy adult volunteers. Each subject underwent low-dose test via 2.5 cm plastic tube via plastic tube and via direct intravenous injection by a metal syringe via direct intravenous injection, and cortisol responses were determined.

    In this study, Cosyntropin was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Cosyntropin.

    Summary
    Mean adrenocorticotropic hormone 1-24 concentration did not differ significantly when flushed via plastic tube or measured in the aliquot solution (P = 0.25).
    1 context sentence
    Summary · context
    We evaluated in vitro if adrenocorticotropic hormone was absorbed in a 2.5 cm plastic tube by measuring adrenocorticotropic hormone 1-24 concentration in a 1 μg/ml adrenocorticotropic hormone aliquot solution before and after being flushed through the plastic tube.
