Abstract

The invention relates to the technical field of medicine, and discloses a suspensoid of sodium carbosulfonate for injection and a preparation method thereof. Composition, the parts by weight of each component are: 1 part of sodium carbosulfonate; 1.5-8.5 parts of a pharmaceutically acceptable biological carrier; 0.1-1.8 parts of a stabilizer; and 2-5 parts of a freeze-drying protective agent. The present invention improves the stability and solubility of the sodium carbosulfonate, and there is no obvious change in various indicators detected after long-term storage, ensuring that the product quality is qualified within the validity period; it can be administered slowly for a long time, and the bioavailability is greatly improved. The pharmaceutically acceptable biological carrier, that is, the protein, is degraded in the body, has no toxicity and no immunogenicity, and can effectively improve the therapeutic index of the drug, reduce the toxicity of the drug and reduce the side effects of the drug.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a suspension of sodium carbosulfonate for injection and a preparation method thereof. Background technique [0002] Carbazochrome sodium (Carbazochrome sodium) is a sulfonic acid derivative that was modified and modified by Japan Tanabe Pharmaceutical Co., Ltd. in 1992 to modify and modify the chemical structure of epinephrine, and found in the study of structure-activity relationship that the water solubility was increased by about 50 times. Its chemical name is It is 1-methyl-6-oxo-2,3,5,6-tetrahydroindole-5-semicarbazone-2-sodium sulfonate, that is, sodium carbosulfonate, which is a new generation of adrenaline derivatives for hemostasis drug. He stops bleeding by enhancing the elasticity of capillaries, reducing the permeability of capillaries, promoting the activity of thrombin and the dissolution of fibrinogen. Clinically, it can be used for diseases of urinary system, u...
