Atosiban

Atosiban

Atosiban is an antagonist of the natural hormone oxytocin. By blocking the action of oxytocin atosiban prevents uterine contractions and causes the uterus to relax,

and thus helps delaying birth.

Atosiban is used to delay birth in pregnant women who are at least 18 years of age, and who are 24 to33 weeks pregnant, when they show signs that they may give birth pre-term.

The undesirable effects in the women include mainly nausea, vomiting, hyperglycaemia, headache, dizziness, and tachycardia.
