Oxytocin, also known as oxytocin, is a uterine contraction drug that can be extracted or chemically synthesized from the posterior lobe of the pituitary gland of animals. The chemical synthesis does not contain vasopressin, has no pressor effect, and has selective excitatory effect on uterine smooth muscle to enhance its contraction. The uterus in labor is most sensitive to oxytocin (increased estrogen secretion), and the immature uterus is not responsive to this product. Uterine responsiveness to oxytocin is low in the first or second trimester of pregnancy, but increases gradually in the second trimester and peaks before labor. Small doses of Chemicalbook can strengthen the rhythmic contraction of the smooth muscle at the bottom of the uterus, strengthen the contraction force and accelerate the contraction frequency, and the contraction nature is similar to natural labor, and maintain the polarity and symmetry, so it is clinically used for oxytocin and induction of labor. The large dose makes the uterine muscle show tonic contraction, which is clinically used to compress the blood vessels between the muscle fibers, prevent postpartum hemorrhage and postpartum rehabilitation insufficiency, and promote lactation, shrink the mammary duct, and promote milk discharge from the breast, but can not increase the secretion of milk, only promote milk discharge
