<unk>  is to be used in the hospital by prescription only. It can be administered intravenously or intramuscularly. In both cases, the recommended dose for an average adult female is 100ug. Contractile effects of the uterus are apparent within two minutes and can be observed for approximately one hour, though maximum binding occurs about 30 minutes after intramuscular injection. Administration is performed immediately following parturition to minimize risk of postpartum hemorrhage by inducing uterine contractions, increasing muscle tone and thickening the blood. If further uterine stimulation is needed, treatment with other forms of oxytocic uterotonic drugs should be used. Endogenous and synthetic oxytocin has a half-life of approximately 3.5minutes.<unk> , in comparison, has a much longer half-life ranging from 85–100minutes. The bioavailable dose is around 80%. The elimination half-life following intravenous administration is around 40 minutes, though the elimination mechanism is not entirely known. Studies have shown that elimination is only minimally renal (0.7%), but may occur at least partially through enzymatic degradation of peptides, primarily on the C-terminal end. Both elimination and volume of distribution are not dose dependent.
