Oxytocin
Also known as: Pitocin (IV obstetric)
Oxytocin is a nine-amino acid peptide hormone (Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, with a disulfide bridge between Cys1 and Cys6) produced in the hypothalamic paraventricular and supraoptic nuclei. The synthetic form (Pitocin) is FDA-approved as IV/IM injection for labor induction/augmentation and postpartum hemorrhage control. Intranasal oxytocin is NOT FDA-approved and is used off-label or in research settings for social/behavioral indications, where evidence is mixed.

Oxytocin moderates father-infant dynamics during triadic family interaction: A dynamic structural equation modeling approach
Background Touch is a primary way parents communicate and bond with infants. Oxytocin, a neuropeptide that promotes bonding and regulates social responsiveness, may shape how parents touch their infants.

Minimum Effective Dose of Prophylactic Oxytocin Infusion During Cesarean Delivery in Preterm and Term Pregnancy: A Sequential Allocation Dose Finding Study
Background There is a paucity of uterine oxytocin receptors during preterm gestation. Whether this affects the requirement of oxytocin dose for uterine contraction in patients with preterm gestation is not researched.

Attachment, oxytocin, and maternal recollections: Further evidence for the salience hypothesis
Childhood memories featuring primary caregivers are the basis of attachment working models. Oxytocin plays a critical role in attachment bonding and social memory possibly by enhancing the emotional salience of social cues.

The role of serum oxytocin levels in the third trimester of pregnancy in the incidence of postpartum depressive symptoms
Recent studies have explored the relationship between oxytocin and the risk of postpartum depression (PPD), yet the results have been inconsistent and require further investigation. As a result, this study examined the relationship between oxytocin and postpartum depressive symptoms.
