Atosiban

Atosiban is a synthetic oxytocin antagonist, specifically a nonapeptide, that acts by selectively inhibiting the oxytocin receptor. It is primarily used for the prevention and treatment of preterm labor in pregnant women.
Preterm labor is a condition where contractions of the uterus occur before the 37th week of pregnancy, leading to premature birth. Atosiban works by blocking the oxytocin receptors in the uterus, thereby preventing uterine contractions and helping to prolong pregnancy until term.
Atosiban is administered through intramuscular or intravenous injection, depending on the severity of preterm labor and the patient’s individual needs. It is important to closely monitor the progress of the pregnancy and the patient’s condition while using Atosiban, as it may have side effects such as nausea, vomiting, and local pain at the injection site.
