1.MECHANISM OF ACTION
Atosiban functions as a competitive antagonist of oxytocin and vasopressin V1a receptors. By selectively binding to these receptors in uterine tissue, it blocks the action of endogenous oxytocin, preventing the intracellular calcium mobilization that triggers uterine contractions. This receptor-level inhibition effectively suppresses preterm uterine activity without interfering with normal labor processes at term, providing targeted tocolytic action with minimal systemic effects.
