Carbetocin

Intravenous, Intramuscular injection
Written by Peptide Association Editorial TeamMedically reviewed by Ian Justl Ellis, MD, CPTLast reviewed Editorial policy

Overview

A long-acting synthetic analog of oxytocin with a modified disulfide bridge that confers resistance to enzymatic degradation. Carbetocin has a half-life of approximately 40 minutes compared to 3-5 minutes for oxytocin, providing sustained uterotonic activity after a single injection.

Mechanism of Action

It selectively binds oxytocin receptors in the myometrium, promoting uterine contraction and reducing postpartum blood loss.

Research Summary & Key Findings

WHO recommends heat-stable carbetocin for prevention of postpartum hemorrhage in settings where oxytocin cold chain cannot be maintained. CHAMPION trial (Widmer et al., NEJM, 2018) demonstrated non-inferiority to oxytocin for preventing blood loss at caesarean delivery. Approved in over 30 countries; not yet FDA-approved in the United States.

No lawful pathway today

Carbetocin is not FDA-approved and does not currently have a lawful prescription or compounding pathway in the United States, so there is nothing for us to sell you here and no consultation to book. That can change: eight peptides moved back to a lawful pathway in February 2026.
