Atosiban (trade names Tractocile, Antocin, Atosiban SUN) is a nonapeptide, desamino-oxytocin analogue, competitive vasopressin/oxytocin receptor antagonist used as a labour repressant (tocolytic) to halt premature labour. Atosiban inhibits the oxytocin-mediated release of inositol trisphosphate from the myometrial cell membrane resulting in reduced release of intracellular, stored calcium from the sarcoplasmic reticulum of myometrial cells as well as reduced influx of Ca2+ from the extracellular space through voltage-gated channels. In addition, atosiban suppresses oxytocin-mediated release of prostaglandins PGE and PGF from the decidua (Sanu & Lamont 2010, Kim et al. 2019). Atosiban antagonises uterine contractions and induces uterine quiescence. (Akerlund et al. 1985, Bossmar et al. 1994).
