Overview

A nine-amino acid cyclic neuropeptide produced in the hypothalamus and released from the posterior pituitary. Oxytocin mediates uterine contractions during labor, milk ejection during lactation, and social bonding behaviors.

Mechanism of Action

It modulates the HPA stress axis, reduces cortisol, and has anxiolytic properties. Intranasal administration reaches the CNS through olfactory and trigeminal nerve pathways..

Research Summary & Key Findings

FDA-approved (Pitocin) for labor induction and postpartum hemorrhage. Clinical trials investigating efficacy in autism spectrum disorder, social anxiety, and PTSD show mixed but promising results. Intranasal oxytocin improved social cognition and reduced amygdala reactivity in clinical studies (Domes et al., Biological Psychiatry, 2007).
