Results from this study2

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

Natural levels measured2

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)Mechanism

    In adult male rats, acute citalopram increased the body's own plasma oxytocin levels.

    In plain wordsIn rats, a single dose of the antidepressant citalopram raised the body's own oxytocin level in blood.

    Summary · context
    Thus. in the present study we examined effects of the SSRI citalopram (20 mg/kg i.p.) on plasma oxytocin, acutely and upon repeated administration, in adult male Sprague-Dawley rats.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.

  2. 02AnimalEndogenous levelAnimal study (in vivo)Mechanism

    In adult male rats, 14 days of citalopram did not reduce the oxytocin-releasing effect of a challenge dose of the SSRI zimeldine.

    In plain wordsIn rats, 14 days of citalopram did not weaken the rise in the body's own oxytocin after a second SSRI dose.

    Summary
    Administration of citalopram for 14 days did not attenuate the oxytocin-releasing effect to a challenge dose of the SSRI zimeldine (20 mg/kg s.c.)
