Oxytocin is an oxytocin hormone preparation that is used to trigger or strengthen uterine contractions if contractions are weak or do not occur by themselves. This drug is also used to ease bleeding after childbirth.
Oxytocin hormone preparations have similar functions to the natural oxytocin hormone produced by the body. Natural oxytocin is produced in the hypothalamus and released into the bloodstream by the pituitary gland in the brain. This hormone has many functions in the body, one of which is to trigger uterine contractions.
During the labor process, contractions are needed so that the baby can come out of the womb. Meanwhile, when labor is completed, uterine contractions are needed to restore the shape of the uterus and stop the bleeding.
In addition to the birthing process, this hormone preparation can also be used in the event of a miscarriage . It is also used to stimulate uterine contractions so that the fetal tissues come out immediately and the bleeding stops.
Brands of oxytocin: Decatosin , Induxin , Oxyla, Oxytocin, Protocin, Santocyn, Syntocinon, Tiacinon.
