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, 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. 01AnimalNot a test of Vasoactive intestinal peptide (VIP, aviptadil) aloneAnimal study (in vivo)Mechanism

    In chicks, the PAC1 antagonist PACAP (6-38) did not attenuate the anorexigenic effect of VIP.

    In plain wordsIn chicks, a PAC1 receptor blocker did not reduce the appetite-lowering effect of VIP.

    Summary
    ICV co-injection of PACAP (6-38), a PAC1 receptor antagonist, attenuated the anorexigenic effect of PACAP but not VIP.

    Summary
    On the other hand, ICV co-injection of [D-p-Cl-Phe6, Leu17]-VIP, a VPAC receptor antagonist, did not affect the effects of both peptides.
