Carbetocin (trade name Duratocin) is an eight amino acid long analogue of oxytocin (a nonapeptide) with improved in vivo stability over oxytocin. Carbetocin primarily agonizes peripherally expressed oxytocin receptors.

Application | Carbetocin is a drug used to control postpartum hemorrhage, bleeding after giving birth, since it causes contraction of the uterus. |
Activity | Agonist |
Biological Activity | Carbetocin acetate, an oxytocin (OT) analogue, is an oxytocin receptor agonist with a Ki of 7.1 nM. Carbetocin acetate has high affinity to chimeric N-terminus (E1) of the oxytocin receptor (Ki=1.17 μM). Carbetocin acetate has the potential for postpartum hemorrhage research. Carbetocin acetate can crosse the blood-brain barrier and produces antidepressant-like activity via activation of oxytocin receptors in the CNS. |
Target | Oxytocin Receptor |
