Results from this study3

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

Natural levels measured3

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.

    In male rats, ipsapirone increased plasma oxytocin concentrations.

    In plain wordsIn male rats, the drug ipsapirone raised the body's own oxytocin level in blood.

    Summary · context
    We determined the effect of chronic fluoxetine and desipramine (DMI) on the hormone response to ipsapirone, a 5-HT1A agonist and a potential anxiolytic drug.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Other

    In male rats, chronic fluoxetine significantly inhibited the ipsapirone-induced rise in plasma oxytocin.

    In plain wordsIn male rats, long-term fluoxetine reduced the rise in the body's own oxytocin level caused by ipsapirone.
