Indications & Usage
INDICATIONS AND USAGE IMPORTANT NOTICE Elective induction of labor is defined as the initiation of labor in a pregnant individual who has no medical indications for induction. Since the available data are inadequate to evaluate the benefits-to-risks considerations, Pitocin is not indicated for elective induction of labor. Antepartum: Pitocin is indicated for the initiation or improvement of uterine contractions, where this is desirable and considered suitable for reasons of fetal or maternal concern, in order to achieve vaginal delivery. It is indicated for (1) induction of labor in patients with a medical indication for the initiation of labor, such as Rh problems, maternal diabetes, preecl…
Clinical Pharmacology
CLINICAL PHARMACOLOGY Uterine motility depends on the formation of the contractile protein actomyosin under the influence of the Ca 2+ -dependent phosphorylating enzyme myosin light-chain kinase. Oxytocin promotes contractions by increasing the intracellular Ca 2+ . Oxytocin has specific receptors in the myometrium and the receptor concentration increases greatly during pregnancy, reaching a maximum in early labor at term. The response to a given dose of oxytocin is very individualized and depends on the sensitivity of the uterus, which is determined by the oxytocin receptor concentration. However, the physician should be aware of the fact that oxytocin even in its pure form has inherent pre…
Contraindications & Precautions
CONTRAINDICATIONS Antepartum use of Pitocin is contraindicated in any of the following circumstances: Where there is significant cephalopelvic disproportion; In unfavorable fetal positions or presentations, such as transverse lies, which are undeliverable without conversion prior to delivery; In obstetrical emergencies where the benefit-to-risk ratio for either the fetus or the mother favors surgical intervention; In fetal distress where delivery is not imminent; Where adequate uterine activity fails to achieve satisfactory progress; Where the uterus is already hyperactive or hypertonic; In ca…

Drug Interactions
Drug Interactions Severe hypertension has been reported when oxytocin was given three to four hours following prophylactic administration of a vasoconstrictor in conjunction with caudal block anesthesia. Cyclopropane anesthesia may modify oxytocin's cardiovascular effects, so as to produce unexpected results such as hypotension. Maternal sinus bradycardia with abnormal atrioventricular rhythms has also been noted when oxytocin was used concomitantly with cyclopropane anesthesia.
Dosage & Administration
DOSAGE AND ADMINISTRATION Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. The dosage of oxytocin is determined by the uterine response and must therefore be individualized and initiated at a very low level. The following dosage information is based upon various regimens and indications in general use. A. Induction or Stimulation of Labor Intravenous infusion (drip method) is the only ac…
