Oxytocin and Pitocin are the same medication with different names. They promote the contraction of uterine smooth muscle by directly stimulating it.In small doses, they enhance the rhythm and intensity of uterine contractions, while large doses can cause the uterine muscle to undergo tetanic contractions. Intravenous infusion has a rapid effect on uterine stimulation but a short duration of action.This medication has a synergistic effect with Misoprostol tablets.In early pregnancy, the uterus is not sensitive to oxytocin, but as the pregnancy progresses, the estrogen secreted by the placenta increases the uterus's sensitivity to oxytocin.It is commonly used for labor induction, augmentation of labor, postpartum hemorrhage, and incomplete uterine involution.Small doses of oxytocin can be used for full - term labor induction after cervical ripening and are suitable for cases of hypotonic uterine dysfunction.It is also a first - line medication for the prevention and treatment of postpartum hemorrhage.
