Pitocin (oxytocin injection, USP) is a sterile, clear, colorless aqueous solution of synthetic oxytocin, for intravenous infusion or intramuscular injection. Pitocin is a nonapeptide found in pituitary extracts from mammals. It is standardized to contain 10 units of oxytocic hormone/mL and contains 0.5% Chlorobutanol, a chloroform derivative as a preservative, 1.65 mg acetic acid and 0.16 mg ammonium acetate as buffers, and with the pH adjusted with acetic acid to achieve a targeted pH of 3.5. Pitocin may contain up to 16% of total impurities. The hormone is prepared synthetically to avoid possible contamination with vasopressin (ADH) and other small polypeptides with biologic activity. Pitocin has the empirical formula C 43 H 66 N 12 O 12 S 2 (molecular weight 1007.19). The structural formula is as follows: Chemical Structure
