Oxytocin Description
Oxytocin, also known as oxytocin, is a uterine contraction drug that can be extracted or chemically synthesized from the posterior pituitary gland of animals. The chemical synthesis product does not contain vasopressin, has no pressure-increasing effect, and has selective excitatory effects on uterine smooth muscle. To strengthen its contraction, the parturient uterus is most sensitive to oxytocin (increased estrogen secretion), the immature uterus is not responsive to this product, the uterus is less responsive to oxytocin in the first or second trimester of pregnancy, and gradually increases in the second trimester. It reached the highest level before delivery. A small dose can strengthen the rhythmic contraction of the smooth muscles at the base of the uterus, making it stronger in contraction, increasing the frequency of contraction, and contracting properties similar to natural labor, and maintaining polarity and symmetry, so it is used clinically to induce labor and induce labor. Large doses cause uterine muscles to exhibit ankylogenic contraction. It is used clinically to compress the blood vessels between muscle fibers to prevent postpartum hemorrhage and postpartum insufficiency. It also promotes lactation, shrinks the ducts of the breast, and promotes milk excretion from the breast, but it cannot increase the secretion of milk. Can only promote breast milk. It should be noted that the dosage and drip rate should be strictly controlled when used for labor induction or chemicalbook induction, so as not to cause ankylosing uterine contraction, causing fetal asphyxia or uterine rupture. It is forbidden when there is cephalopelvic disproportion, improper fetal position or other birth canal abnormalities, poor uterine contraction, history of cesarean section and more than 3 times for banned by women. Oxytocin preparations isolated from the pituitary gland of cattle and pigs occasionally cause allergic reactions. Excessive intravenous drip can cause mild vasodilation and lower blood pressure. The fastest drip rate does not exceed 40 to 60 drops per minute. Slightly higher doses are also used for postpartum hemorrhage, and placental wear. In recent years, it has been found that this product has a good effect on hemoptysis of the lung, and it has a good effect on the relaxation of gastrointestinal function after vagus nerve resection or after abdominal surgery. Oral ineffective, easily destroyed by digestive juice, but can be absorbed by the oral mucosa. Intravenous infusion of 0.01IU can cause physiological contraction of the uterus (with rhythm, polarity, and symmetry) within a short period of time, half life Large doses of only 2.5 to 3 minutes made the uterine muscles to contract. Synergistic effect with prostaglandins.

Oxytocin Function

Oxytocin (Oxt) is a mammalian neurohypophysial hormone. Produced by the hypothalamus and stored and secreted by the posterior pituitary gland, oxytocin acts primarily as a neuromodulator in the brain.
Oxytocin plays an important role in the neuroanatomy of intimacy, specifically in sexual reproduction of both sexes, in particular during and after childbirth; its name, meaning "swift childbirth", comes from Greek, oksys "swift" and , tokos "birth." It is released in large amounts after distension of the cervix and uterus during labor, facilitating birth, maternal bonding, and, after stimulation of the nipples, lactation. Both childbirth and milk ejection result from positive feedback mechanisms.
