Atosiban was introduced in the UK as an injectable inhibitor of preterm labor, a major cause of infant morbidity and mortality. This peptidic oxytocin analog is an antagonist of the vasopressin V1a receptor and of the oxytocin receptor which is found in dramatically increased concentration in the uterine myometrium of pregnant women near term. It competitively inhibited contractions in the pregnant guinea pig uterus induced by oxytocin and vasopressin. In a multicenter, double-blind, placebo-controlled trial, treatment with atosiban caused pregnancy prolongation for up to 7 days in women with more than 28 weeks of gestation. In a comparative clinical trial, atosiban showed a comparable tocolytic action (uterine relaxant) to ritodrine but the former was significantly better tolerated, especially with regards to maternal cardiovascular side effects. In healthy volunteers, plasma levels of atosiban decreased bi-exponentially with an initial and a terminal half-life of 21 min and 1.7h respectively.
The CAS number of Atosiban is 90779-69-4.

Atosiban has been used:as an oxytocin receptor antagonistin the calcium mobilization assay for Z factor determination in uterine myometrium (UT-myo cells) and as a therapeutic agent to inhibit preterm laborto inhibit the activation of oxytocin-receptor-expressing neurons in the parabrachial nucleus of mice (OxtrPBN)
Atosiban is an analogue of oxytocin that is modified at positions 1, 2, 4, and 8. It is a competitive inhibitor of oxytocin binding. Early studies have demonstrated that this drug does decrease and stop uterine contractions. Atosiban is not available for use in the United States.
