Problems solved by technology

According to this process, the production cost is high, and it is difficult to accept clinically
[0020] In addition, compound oxytocin and ergometrine aqueous injections are very unstable, and they have high requirements for storage conditions: even products produced by filter sterilization processes should be protected from light, stored and transported at 2-8°C, which is It brings great inconvenience to clinical use, and the limited production and transportation costs limit the clinical application of this product for water injection

Abstract

The invention relates to a medicine composition, which is characterized by consisting of oxytocin analogue, ergometrine or salt acceptable in pharmacy, a carrier acceptable in preparation process or excipient, antioxygen, a potential of hydrogen (pH)conditioning agent, solubilizer and other auxiliary materials. The medicine composition is used for prevention and cure of postpartum hemorrhage caused by uterine contraction and atony and active management at the third stage of childbirth and is contribute to postpartum functional recovery. The ergometrine and the oxytocin analogue are combined to increase the curative effect and reduce the untoward effect. The dosage form is a freeze-drying mode or a sterile split package mode, high temperature sterilization is avoided in the preparation process, the medicines are stored in a solid state, the integrated antioxygen is added, impurities are decreased, the medicine composition is stable, and storage and transportation at the room temperature are facilitated.

Description

technical field [0001] The invention relates to the prevention and treatment of postpartum hemorrhage caused by uterine atony, active management of the third stage of childbirth and a pharmaceutical composition helpful for postpartum functional recovery, belonging to the technical field of medicine. Background technique [0002] Oxytocin is mainly used clinically for induction of labor, antepartum uterine atony, postpartum hemorrhage and incomplete uterine involution. [0003] Oxytocin can indirectly stimulate the contraction of uterine smooth muscle, simulating the uterine contraction of normal childbirth, resulting in cervical dilatation, and the uterine response to oxytocin gradually increases during pregnancy and reaches its peak at full term. It can also stimulate the contraction of the smooth muscle of the mammary gland, which helps the milk to be discharged from the breast, but does not increase the milk secretion of the mammary gland. [0004] The special anatomical...
