Contra Indications
• Gestational age below 24 or over 33 completed weeks
• Premature rupture of the membranes >30 weeks of gestation
• Intrauterine growth retardation and abnormal fetal heart rate
• Antepartum uterine haemorrhage requiring immediate delivery
• Eclampsia and severe pre-eclampsia requiring delivery
• Intrauterine fetal death
• Suspected intrauterine infection
• Placenta praevia
• Abruptio placenta
• Any other conditions of the mother or fetus, in which continuation of pregnancy is hazardous
• Known hypersensitivity to the active substance or any of the excipients.
Precautions
When Atosiban is used in patients in whom premature rupture of membranes cannot be excluded,
the benefits of delaying delivery should be balanced against the potential risk of chorioamnionitis.
Atosiban has not been used in patients with an abnormal placental site.
There is only limited clinical experience in the use of Atosiban in multiple pregnancies or the
gestational age group between 24 and 27 weeks, because of the small number of patients treated.
Retreatment with Atosiban is possible, but there is only limited clinical experience available with
multiple re-treatments, up to 3 retreatments.
In case of intrauterine growth retardation, the decision to continue or reinitiate the administration of
Atosiban depends on the assessment of fetal maturity.
Monitoring of uterine contractions and fetal heart rate during administration of Atosiban and in case
of persistent uterine contractions should be considered.
As an antagonist of oxytocin, Atosiban may theoretically facilitate uterine
Pregnancy-Lactation
Pregnancy
Atosiban should only be used when pre-term labour has been diagnosed between 24 and 33 completed weeks of gestation.
Breast-feeding
If during pregnancy the woman is already breast-feeding an earlier child, then breast-feeding should be discontinued during treatment with atosiban, since the release of oxytocin during breast-feeding may augment uterine contractility, and may counteract the effect of tocolytic therapy.
In atosiban clinical trials no effects were observed on breast-feeding. Small amounts of atosiban have been shown to pass from plasma into the breast milk of breast-feeding women.
Fertility
Embryo-fetal toxicity studies have not shown toxic effects of atosiban. No studies were performed that covered fertility and early embryonic development
Interactions
Increased risk of pulmonary oedema w/ other tocolytic drugs (e.g. Ca channel blockers, betamimetics)
Side Effects
Side effects of Atosiban :
Nausea, vomiting, headache, dizziness, flushes, tachycardia, hypotension, hyperglycaemia, inj site reactions; insomnia, pruritus, rash, pyrexia. Rarely, uterine haemorrhage and atony.
Mode of Action
Atosiban, a synthetic oxytocin peptide analogue, is a competitive antagonist of oxytocin receptors. It suppresses uterine contractions by decreasing its frequency and the tone of uterine musculature. Additionally, it inhibits the effect of vasopressin.
