Descripción

Application

Atosiban has been used:

• as an oxytocin receptor antagonist
• in the calcium mobilization assay for Z factor determination in uterine myometrium (UT-myo cells) and as a therapeutic agent to inhibit preterm labor
• to inhibit the activation of oxytocin-receptor-expressing neurons in the parabrachial nucleus of mice (Oxtr^PBN)

Biochem/physiol Actions

Atosiban is a peptide oxytocin receptor antagonist.

Atosiban efficiently prevent preterm uterine contractions without any major cardiovascular, pulmonary or central nervous system side effects. It has potential to treat preterm labour.
