Embodiment 1

[0024] Carbetocin acetate (100 μg / ml as carbetocin), 9.0 mg / ml sodium chloride, 0.1% w / v sodium bisulfite, 2% w / v benzyl alcohol, pH adjusted with glacial acetic acid is 3.8, and its preparation process is as follows:

[0025] Weigh carbetocin acetate (calculated as carbetocin 100mg), 9.0g sodium chloride, 1.0g sodium bisulfite, 20.0g benzyl alcohol, dissolve completely with 80% water for injection of the prescribed amount, and dissolve with glacial acetic acid Adjust pH to 3.8, add water for injection to 1000ml. Before filtering, add 5g of activated carbon to the injection, absorb pyrogen for 30 minutes under stirring, decarbonize and filter. The filtrate was filtered through a 0.22 μm titanium rod filter, and then sterilized and filtered through a 0.22 μm microporous membrane, filled into 1ml sterile ampoules, and sealed. Make each tube equivalent to 100 μg carbetocin.

Abstract

The invention relates to a more-stable carbetocin acetate injection. The preparation consists of carbetocin acetate, an isoosmotic adjusting agent, a pH value regulating agent, an antioxidant, a local analgetic and a solvent, wherein the addition of the antioxidant can improve the stability of the preparation, and the addition of the local analgetic can relieve pains of a patient but does not affect the basic remedy. The process for preparing the preparation mainly comprises the following steps: weighing, dissolving, adsorbing a heat source by activated carbon, filtering, filtering by a terminal, subpackaging and sealing. The preparation is used for preventing and treating insufficient uterus tension and postpartum hemorrhage. The preparation has stable quality and an exact curative effect, and can be accepted by patients.

Description

Technical field: [0001] The invention relates to the field of preparations, in particular to a more stable carbetocin acetate injection. Background technique: [0002] Carbetocin is a synthetic long-acting nonapeptide analogue of oxytocin with agonist properties. A single dose intravenously may be administered immediately after cesarean section under epidural or spinal anesthesia to prevent uterine hypotonia and postpartum hemorrhage. [0003] The clinical and pharmacological properties of carbetocin are similar to those of naturally occurring oxytocin. Like oxytocin, carbetocin binds to the oxytocin receptors of uterine smooth muscle, causing rhythmic contractions of the uterus, increasing its frequency and increasing uterine tension on the basis of the original contractions. Oxytocin receptor levels in the uterus are low in the non-pregnant state, increase during pregnancy, and peak at parturition. Carbetocin therefore has no effect on the non-pregnant uterus, but has p...
