Product Information

• Name: Atosiban
• Synonyms: c[Mpr-D-Tyr(Oet)-Ile-Thr-Asn-Cys]-Pro-Orn-Gly-NH2
• Brand: Biosynth
• Description: Atosiban is a drug that is used to prevent preterm labor in pregnant women. It works by inhibiting the release of oxytocin from the hypothalamus, which decreases contractions and relaxes the uterus. Atosiban has been shown to be effective in decreasing the incidence of preterm birth in women with bacterial vaginosis who are at high risk for preterm delivery (e.g., those with a history of preterm labor). Clinical trials have shown that it may also be useful as an adjunct therapy in treating women with unexplained infertility and recurrent pregnancy loss. The drug binds to receptors on cells, which inhibits the release of intracellular calcium, thus preventing contraction of uterine muscle cells. This effect can be reversed by administration of estradiol benzoate or other drugs that affect receptor activity. It is not known whether atosiban affects fetal development during pregnancy or if it causes any effects on the mother's heart rate or body mass index after childbirth.
