Mechanism of action

Misoprostol acts as a synthetic prostaglandin that stimulates uterine smooth muscle contraction and softens the cervix by increasing local prostaglandin receptor signaling. The modified-release pessary formulation delivers the drug directly to the uterus over an extended period, allowing sustained local effects while minimizing systemic exposure. This mechanism facilitates labor induction and cervical preparation in obstetric settings.
