Atosiban acetate is primarily used in obstetrics to manage preterm labor. It acts as an oxytocin receptor antagonist, effectively inhibiting premature uterine contractions. This helps to delay birth, providing critical time for administering corticosteroids to enhance fetal lung maturity or for transferring the mother to a facility with specialized neonatal care. It is administered intravenously and is particularly valuable in cases where other tocolytic agents may be contraindicated. Its targeted action on the oxytocin pathway makes it a safer option for both the mother and the fetus, reducing the risk of preterm delivery and associated complications.
