Description and Uses
Oxytocin is a peptide hormone containing nine amino acids secreted and synthesized by the paraventricular and supraoptic nuclei of the hypothalamus and stored and released by the neurohypophysis. It acts in females by inducing uterine contractions during parturition and stimulating milk ejection by the mammary glands. No actions in males are known. Synthetic derivatives of oxytocin are used to induce labor and for therapeutic abortions. In recent years the safety of oxytocin has been greatly enhanced by the use of continuous maternal and fetal monitoring and by the use of controlled intravenous infusion of the drug.
Oxytocin is used as a peptide hormone that acts predominantly as a neurotransmitter; stimulates uterine contraction and lactation, increases Na+ excretion; stimulates myometrial GTPase and phospholipase C.
