Carbetocin
Carbetocin is an oxytocin receptor agonist with prolonged duration. It triggers a sustained contraction of the uterus after birth, preventing atonic hemorrhage — unlike oxytocin, without a multi-hour infusion.
Oxytocin
Oxytocin is synthesised in the hypothalamus and released via the posterior pituitary. Peripherally it binds the oxytocin receptor, a G-protein-coupled receptor, and through the phospholipase-C cascade and calcium release triggers contraction of uterine smooth muscle and milk ejection — the pharmacological basis of the obstetric approval. Centrally, oxytocin acts as a neuromodulator and has been linked to social bonding, trust and modulation of stress and anxiety circuits. Its central effects in humans are mechanistically incompletely understood, particularly because it is unclear to what extent peripherally or intranasally administered oxytocin crosses the blood-brain barrier.

Frequently asked questions
- What is the difference between Carbetocin and Oxytocin?
- Carbetocin is classified as "Onderzoek (overig)", while Oxytocin is classified as "Onderzoek (overig)". Carbetocin: Carbetocin is a long-acting synthetic oxytocin analog (half-life ~40 minutes). It prevents postpartum hemorrhage as a single injection. Approved in Canada and the UK among others, NOT in the US. Oxytocin: Oxytocin is an endogenous nonapeptide hormone of the posterior pituitary. In synthetic form (Pitocin, Syntocinon) it has been approved for decades to induce and augment labour and to control postpartum uterine bleeding. Strictly separate from this is intranasal use to influence social behaviour, trust, anxiety or autism symptoms: this use is unapproved, purely experimental, and yields inconsistent and often negative results in controlled trials. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Carbetocin or Oxytocin?
- The highest available evidence level is "Humane RCT" for Carbetocin and "Humane RCT" for Oxytocin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Carbetocin and Oxytocin in Germany and the United States?
- Duitsland: Carbetocin — Op recept, Oxytocin — Op recept. Verenigde Staten: Carbetocin — Niet goedgekeurd, Oxytocin — Op recept. These are factual summaries with source and review date on the individual pages.
