Carbetocin is an obstetric drug used to control postpartum hemorrhage and bleeding after giving birth.

Pro8-Oxytocin, a modified oxytocin (OXT) ligand, elicits more potent and efficacious responses at primate OXTR and induces stronger behavioral effects compared to the standard mammalian OXT ligand (Leu8-Oxytocin). It demonstrates lower efficacy than Vasopressin (AVP) at human AVPR1a, yet shows a higher efficacious response at marmoset AVPR1a [1].

Atosiban acetate (RW22164) is an inhibitor of the hormones oxytocin and vasopressin. It is used as an intravenous medication as a labour repressant (tocolytic) to halt premature labor. Atosiban acetate (RW22164) inhibits the oxytocin-mediated release of inositol trisphosphate from the myometrial cell membrane. As a result, there is reduced release of intracellular, stored calcium from the sarcoplasmic reticulum of myometrial cells, and reduced influx of Ca2+ from the extracellular space through voltage gated channels. In addition, Atosiban acetate (RW22164) suppresses oxytocin-mediated release of PGE and PGF from the decidua. In human pre-term labor, atosiban, at the recommended dosage, antagonizes uterine contractions and induces uterine quiescence. The onset of uterus relaxation following atosiban is rapid, uterine contractions being significantly reduced within 10 minutes to achieve stable uterine quiescence.

Oxytocin acetate (α-Hypophamine acetate) is a mammalian neurohypophysial hormone, a ligand of oxytocin receptor.

Pro8-Oxytocin TFA, a modified oxytocin (OXT) ligand, exhibits greater potency and efficacy than the standard mammalian OXT ligand, Leu8-Oxytocin, at primate OXTR and elicits more pronounced behavioral effects. Compared to vasopressin (AVP), Pro8-Oxytocin TFA has a lower efficacious response at human AVPR1a, yet shows a higher efficacy at the marmoset AVPR1a [1].

(Val3,Pro8)-Oxytocin functions primarily as a Gq-dependent pathway agonist and exhibits secondary activity as a reduced efficacy agonist for β-arrestin recruitment and receptor-mediated endocytosis at the oxytocin receptor (OXTR) [1].
