Carbetocin is a drug used to control postpartum hemorrhage, bleeding after giving birth, since it causes contraction of the uterus.
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.http://www.creative-peptides.com/product/carbetocin-acetate-item-10-101-42-24.html
