A synthetic analog of vasopressin (antidiuretic hormone) FDA-approved for diabetes insipidus, bedwetting, and hemophilia A. One of the most widely prescribed peptide drugs globally.
A naturally occurring nonapeptide produced in the hypothalamus and released by the pituitary gland. Known as the 'bonding hormone' for its role in social bonding, trust, and attachment. Also has established medical uses in obstetrics. Growing interest in intranasal oxytocin for social anxiety, autism spectrum disorder, and relationship enhancement.
Selectively activates V2 vasopressin receptors in the kidney collecting ducts, increasing water reabsorption and concentrating urine. Also releases von Willebrand factor and Factor VIII from endothelial stores, aiding blood clotting.
Binds to oxytocin receptors throughout the brain and body. In the brain, modulates the limbic system to reduce fear and increase trust and social engagement. Peripherally, stimulates uterine contractions (obstetric use) and milk ejection. Intranasal delivery allows direct access to the brain via the olfactory pathway.

FDA-approved in multiple formulations: DDAVP (nasal spray, injection, tablets), Stimate (nasal spray for bleeding disorders), Nocdurna (sublingual for nocturia). Generic available.
FDA-approved as Pitocin for obstetric use (labor induction, postpartum hemorrhage). Intranasal oxytocin for psychiatric and social indications is investigational — not FDA-approved for these uses. Available through compounding pharmacies with a prescription for off-label intranasal use.
