Application

Atosiban has been used:
  • as an oxytocin receptor antagonist
  • in the calcium mobilization assay for Z factor determination in uterine myometrium (UT-myo cells) and as a therapeutic agent to inhibit preterm labor
  • to inhibit the activation of oxytocin-receptor-expressing neurons in the parabrachial nucleus of mice (OxtrPBN)

Actions biochimiques/physiologiques

Atosiban efficiently prevent preterm uterine contractions without any major cardiovascular, pulmonary or central nervous system side effects. It has potential to treat preterm labour.
Atosiban is a peptide oxytocin receptor antagonist.

Reconstitution

Reconstitute in deionized water at not less than 100 μg/mL, which can then be diluted into aqueous vehicle of choice. Solutions may be stored at 2-8 °C for up to seven days. For extended storage, add a carrier protein of 0.1% human serum albumin or bovine serum albumin and freeze in working aliquots at −20 °C.
