Results from this study5

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

Natural levels measured5

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01AnimalEndogenous levelAnimal study (in vivo)Pharmacokinetics

    In rabbits on a high sodium diet, the metabolic clearance rate of the body's own VIP was significantly higher than on a low sodium diet during vehicle infusion (P < 0.01).

    In plain wordsIn rabbits, the body's own VIP was cleared faster on a high sodium diet than on a low sodium diet.

    Summary
    The metabolic clearance rate of vasoactive intestinal peptide was significantly higher in rabbits on the high sodium diet during both vehicle control (P < 0.01) and angiotensin II (P < 0.05) infusion.
    1 context sentence
    Summary · context
    We determined the metabolic clearance rate and theoretical secretion rate of vasoactive intestinal peptide in rabbits on low sodium (high circulating angiotensin II) and high sodium (low circulating angiotensin II) diets with and without simultaneous angiotensin II infusion.

    This result measures the body's own Vasoactive intestinal peptide (VIP, aviptadil). Nobody was given the peptide. It is not evidence about taking it.

    In rabbits on a high sodium diet, the metabolic clearance rate of the body's own VIP was significantly higher than on a low sodium diet during angiotensin II infusion (P < 0.05).

    In plain wordsIn rabbits given angiotensin II, the body's own VIP was cleared faster on a high sodium diet than on a low sodium diet.

  3. 03AnimalEndogenous levelAnimal study (in vivo)Pharmacokinetics

    In rabbits on low and high sodium diets, angiotensin II infusion decreased the metabolism of the body's own VIP (P < 0.01 in both).

    In plain wordsIn rabbits, angiotensin II slowed the breakdown of the body's own VIP on both low and high sodium diets.
