Atosiban acetate, the acetate salt of Atosiban (RW-22164; Tractocile; RWJ22164), is a novel and potent peptide-based oxytocin and vasopressin antagonist with the potential to be used for spontaneous preterm labor. It is a nonapeptide, desamino-oxytocin analogue, and a competitive vasopressin/oxytocin receptor antagonist (VOTra). Atosiban inhibits the oxytocin-mediated release of inositol trisphosphate from the myometrial cell membrane.
