Also known as: Pitocin, Syntocinon, love hormone, OT
Oxytocin (Pitocin/Syntocinon) has an IV plasma half-life of approximately 1–6 minutes per the FDA Pitocin prescribing information (NDA 018261), attributed to rapid degradation by oxytocinase (leucine aminopeptidase family enzymes) in plasma, kidney, and placenta. Subcutaneous half-life is estimated at 30–60 minutes due to slower depot absorption. FDA-approved only for obstetric use (IV infusion). Intranasal and subcutaneous uses for social/cognitive and off-label applications are not FDA-approved. Intranasal delivery provides partial CNS penetration via olfactory/trigeminal routes.
