Embodiment 1

[0211] Embodiment 1: Preparation of carbetocin injection

[0212] formula:

[0213] Carbetocin

0.1 mg,

Dextran 40

10mg,

pH regulator

Appropriate amount, adjust the pH value to 4.0,

Water for Injection

Appropriate amount, add to 1ml.

[0214] Preparation method:

[0215] (1) Dissolve each solid excipient and carbetocin in an appropriate amount of water for injection, so that the volume of the solution reaches 80% of the theoretical prescription volume (ie about 0.8ml, the same below);

[0216] (2) Regulate the pH value of the solution to a specified value with an acid-base regulator;

[0217] (3) Add water for injection to 1ml, add 0.05% activated carbon to the liquid medicine, absorb pyrogen for 30 minutes under stirring, decarburize 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, and 1 ml of the liquid medicine was fille...

Abstract

The invention belongs to the technical field of medicine, and relates to an oxytocin analogue, in particular to a carbetocin, and more particularly to a carbetocin injection with excellent pharmaceutical properties. The carbetocin of the present invention can be used for selective epidural or spinal anesthesia after caesarean section to prevent uterine atony and postpartum hemorrhage. The invention also relates to a preparation method of carbetocin injection. Further, the present invention also relates to the medical application of carbetocin injection. In particular, the present invention relates to carbetocin injection, which contains carbetocin, carbohydrates and water for injection.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to an oxytocin analogue, in particular to a carbetocin, and more particularly to a carbetocin injection with excellent pharmaceutical properties. The carbetocin of the present invention can be used for selective epidural or spinal anesthesia after caesarean section to prevent uterine atony and postpartum hemorrhage. The invention also relates to a preparation method of carbetocin injection. Further, the present invention also relates to the medical application of carbetocin injection. Background technique [0002] Carbetocin, molecular formula C45H69N11O12S, molecular weight 988.16, CAS registration number 37025-55-1, chemical name: deamin-2-oxo-methyltyrosine-1-κ oxytocin, its chemical structural formula : [0003] [0004] Carbetocin is a synthetic long-acting nonapeptide analog of oxytocin with agonist properties. A single dose intravenously may be administered immediately ...
