Oxytocin

Peptide Hormoneprescription

Endogenous nonapeptide and prescription uterotonic. Intranasal oxytocin has also been investigated experimentally for behavioral indications, but trial results are mixed and it is not a general social-cognition therapy.

Pharmacokinetic model

A route-level PK model for oxytocin is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.

Research behind this entry

  1. The effect of oxytocin nasal spray on social interaction in young children with autism: a randomized clinical trial Guastella AJ, Boulton KA, Whitehouse AJO, Song YJ, Thapa R, Gregory SG, Pokorski I, Granich J, DeMayo MM, Ambarchi Z, Wray J, Thomas EE, Hickie IB · Molecular Psychiatry, 2023 DOI

    Twelve-week randomized trial in 87 children found no overall improvement on the primary social-responsiveness outcome. A younger-age subgroup signal was exploratory and did not establish efficacy for the population.

  2. Plasma pharmacokinetics of intravenous and intranasal oxytocin in nonpregnant adults Shafer SL, Ririe DG, Miller S, Curry RS, Hsu DT, Sullivan GM, Eisenach JC · British Journal of Anaesthesia, 2025 DOI

    LC-MS population analysis supported a two-compartment IV model but found about 0.7% intranasal bioavailability and large between-person variability. That route divergence prevents a single generic profile.
