Carbetocin (Duratocin) vs Vasopressin (Vasostrict)

An educational, source-based comparison of Carbetocin (Duratocin) and Vasopressin (Vasostrict) — how each peptide works, what it's researched for, and what to know before going deeper.

Oxytocin Analog · Obstetrics
Carbetocin (Duratocin)

Long-acting oxytocin analog for postpartum hemorrhage prevention.

Mechanism

Synthetic, heat-stable oxytocin analog with longer half-life. Stimulates uterine contraction following delivery to prevent postpartum hemorrhage.

Research areas
  • Postpartum hemorrhage prevention (C-section, vaginal delivery)
Considerations
  • FDA-approved (also widely used internationally).
  • Single-dose use only.

Vasopressor · Hormonal
Vasopressin (Vasostrict)

Nonapeptide hormone used for vasodilatory shock.

Mechanism

Endogenous nonapeptide that activates V1 vascular receptors to cause vasoconstriction and V2 renal receptors for water reabsorption. Used to raise blood pressure in catecholamine-resistant shock.

Research areas
  • Septic shock
  • Cardiac arrest (historical)
  • Diabetes insipidus
Considerations
  • FDA-approved.
  • Ischemic complications possible at high doses.
