Results from this study3

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

Studies that did not test the peptide alone3

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.

  1. 01HumanNot a test of Cosyntropin aloneNon-randomized trialActivity measurement

    In healthy adults, the cortisol increment was higher after afternoon versus morning cosyntropin testing (11.89±3.50 versus 7.71±3.12 μg/dL, P=0.002).

    In plain wordsIn healthy adults, afternoon cosyntropin testing increased cortisol from baseline more than morning testing.

    Summary
    however, mean absolute SC-concentration increment between baseline and 30-minute time point was higher in the afternoon than in the morning (11.89±3.50 and 7.71±3.12 μg/dL, respectively; P=0.002).

    Thirteen healthy adult volunteers were recruited for the study.
    Summary · context
    Each subject underwent morning and afternoon LDT via 25 mm plastic intravenous line tube.

    Summary
    Subsequently, LDT resulted in comparable morning and afternoon 30-minute SC (21.33±3.08 and 21.08±3.43 μg/dL, respectively; P=0.782) and SFC concentration (0.939±0.256 and 1.036±0.372 μg/dL, respectively; P=0.463).
