  1. 01HumanNon-randomized trialActivity measurement

    In subjects with intact adrenal function, animal-origin ACTH1-39 produced cortisol increases comparable to synthetic ACTH1-18 at 1, 2, and 6 hours.

    In plain wordsIn subjects with intact adrenal function, ACTH1-39 increased cortisol similarly to synthetic ACTH1-18.

    Summary
    Forty units of 1-39 ACTH of animal origin or 0.4 mg of synthetic 1-18 ACTH administered at 8 A.M. via either the intramuscular route to 10 subjects with intact adrenocortical function produced comparable increases in plasma cortisol at 1, 2, and 6 hours.
  2. 02HumanNon-randomized trialActivity measurement

    In subjects, intravenous crystalline ACTH1-39 increased cortisol for at least 6 but less than 12 hours, versus 16 to less than 24 hours with intramuscular gel.

    Summary
    The increase in plasma cortisol lasted at least 6 hours but less than 12 hours after intravenous crystalline 1-39 ACTH and at least 16 hours but less than 24 hours after the same dose of 1-39 ACTH administered as a depot gel via the intramuscular route.
  3. 03HumanNon-randomized trialActivity measurement

    In subjects, neither intravenous nor intramuscular ACTH1-39 produced a cortisol increase still evident at 24 hours.

    In plain wordsIn subjects, cortisol increases after intravenous or intramuscular ACTH1-39 were no longer evident at 24 hours.

    Summary
    However, neither intravenous nor the intramuscular injection of 1-39 ACTH produced increases that were still evident at 24 hours.
