Atosiban is a combined receptor antagonist of oxytocin and vasopressin V1A. The structure of oxytocin receptor and vasopressin V1A receptor is similar. When the oxytocin receptor is blocked, oxytocin can still exert its effect through the V1A receptor. Therefore, it is necessary to block the above two receptor pathways with the Chemicalbook. A single antagonist of one receptor can effectively inhibit uterine contraction. This is also one of the main reasons why β-receptor agonists, calcium channel blockers and prostaglandin synthase inhibitors cannot effectively inhibit uterine contractions.
Atosiban, as a combined receptor antagonist of oxytocin and vasopressin V1A, has a chemical structure similar to the two, and has a high affinity with the receptor, competitively binding to oxytocin and vasopressin V1A receptors , Thereby blocking the way of action of oxytocin and vasopressin, reducing uterine contractions.
