Abstract

The invention discloses a carbazochrome sodium sulfonate freeze-dried powder injection and preparation method thereof, and the carbazochrome sodium sulfonate freeze-dried powder injection is composed of carbazochrome sodium sulfonate, mannitol, and buffer salts, wherein the solvent for preparation is injection water. Through a great number of tests, the problems of unstable pH value during the preparation of the carbazochrome sodium sulfonate freeze-dried powder injection and unqualified clarity during storage are solved only by adding buffer salts. The process of the prescription of the present invention overcomes the disadvantages of the prior arts, and provides a carbazochrome sodium sulfonate freeze-dried powder injection with the advantages of simple prescription, guaranteed quality and good stability; and is suitable for clinical applications. The present invention also achieves the advantages that: (1) the prescription is simple, wherein in addition to using carbazochrome sodium sulfonate as the main drug, the excipients in the prescription are only mannitol and buffer salts; (2) raw materials and excipients used in the prescription are all medicinal injection grade prescribed by the State Food and Drug Administration so as to eliminate the risk of unpredictable adverse reactions caused by non-pharmaceutical excipients; (3) the stability is good and the prescription is convenient for transportation and storage; (4) no hemolysis, agglutination, irritation, or allergic reactions are observed throughout special safety tests such as allergenicity, hemolytic activity andvascular irritation tests.

Description

technical field [0001] The invention relates to a freeze-dried powder injection of sodium carbosulfonate and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Sodium carbosulfonate is a new type of hemostatic drug, which is a commonly used hemostatic drug in clinical practice. The chemical name of sodium carbosulfonate is: 1-methyl-6-oxo-2,3,5,6-tetrahydroindole-5-semicarbazone-2-sulfonic acid sodium salt trihydrate, and its chemical The structural formula is: [0003] [0004] The mechanism of the pharmacological action of sodium carbosulfonate is to increase capillary elasticity, reduce permeability, and increase its contractility; promote the activity of thrombin and the dissolution of fibrinogen, and then form a thrombus at the bleeding site to achieve the purpose of hemostasis. The drug is widely used clinically for bleeding in urinary system, upper gastrointestinal tract, respiratory tract ...
