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, Vasoactive intestinal peptide (VIP, aviptadil) 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 Vasoactive intestinal peptide (VIP, aviptadil).

  1. 01HumanNot a test of Vasoactive intestinal peptide (VIP, aviptadil) aloneNon-randomized trialMechanism

    In human skin, the VIP fragment VIP(10-28) augmented vasodilation to exogenous VIP versus control, instead of blocking it.

    In plain wordsIn human skin, the VIP fragment VIP(10-28) increased the widening of blood vessels caused by VIP, compared with a control site.

    Summary
    VIP(10-28) augmented vasodilation to exogenous VIP (P < 0.05 vs. control)
    2 context sentences
    Summary · context
    Study 1 (n = 12) examined whether VIP(10-28) antagonizes vasodilation to exogenous VIP via inhibition of NO-dependent mechanisms.
    Summary · context
    The present study aimed to further examine the specific role for VIP in AVD by using VIP(10-28) to antagonize VIP-mediated dilation in the presence of NO synthase (NOS) inhibition and an H1 antagonist.

    In this study, Vasoactive intestinal peptide (VIP, aviptadil) 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 Vasoactive intestinal peptide (VIP, aviptadil).

  2. 02HumanNot a test of Vasoactive intestinal peptide (VIP, aviptadil) aloneNon-randomized trialMechanism

    In human skin, H1-receptor antagonists had no effect on the dilation augmented by VIP(10-28) during hyperthermia.

    In plain wordsIn human skin, blocking histamine H1 receptors did not change the extra vessel widening seen with VIP(10-28) during heat.
