Mechanism of action

Oxytocin is a neurohypophyseal hormone that acts on G-protein coupled oxytocin receptors located on uterine smooth muscle and mammary gland myoepithelial cells. In obstetrics, it induces or augments labor by triggering rhythmic uterine contractions. In lactation, it facilitates milk ejection by contracting the myoepithelial cells surrounding the alveoli.
