Problems solved by technology

The disadvantages of using organic solvents are: on the one hand, it increases the production process steps and production costs, and increases energy consumption;
[0007] In a word, whether it is to make solid sodium fructose diphosphate through the fine-baking process, or to make solid sodium fructose diphosphate by the method in the Chinese patent whose application publication number is CN1650871A, a large amount of organic solvents are needed in the process; in addition, In the process of preparing sodium fructose diphosphate injection, it is necessary to dissolve the solid sodium fructose diphosphate and follow-up operations to obtain the target product-sodium fructose diphosphate injection. This process requires a certain period, and usually The solid sodium fructose diphosphate needs to be transported to the processing place of sodium fructose diphosphate injection, and the transportation cost is high during the process

Abstract

The invention discloses a preparation method of fructose sodium diphosphate injection, which comprises the following steps: S1, dissolving disodium hydrogen phosphate, sodium dihydrogen phosphate, glucose and phosphoric acid in water to prepare a reaction liquid, mixing with beer yeast, stirring and reacting to obtain a raw material liquid containing fructose sodium diphosphate; 2, filter that rawmaterial liquid plate frame; S3, adsorbing and purifying the solid-liquid separated raw liquid in S2 by anionic resin to obtain resin extract containing fructose sodium diphosphate; 4, decolorizing and filtering, decolorize that resin extract solution by activated carbon, and filtering and decarburizing; 5, carrying out initial concentration on that decolorization filtrate in S4, washing and desalinate the decolorization filtrate with water, and finally pressurizing the decolorization filtrate to concentrate the specific gravity of the decolorization filtrate to more than 1.05 g / ml; 6, filterthat concentrated drug solution to obtain RO solution; 7, filter that RO solution in S6, diluting, filter, and filling to obtain sterile fructose sodium diphosphate injection. The invention has the advantages of greatly reducing the use amount of the organic solvent in the preparation process and reducing the production cost.

Description

technical field [0001] The invention relates to the technical field of medicine preparation, more specifically, it relates to a preparation method of sodium fructose diphosphate injection. Background technique [0002] Fructose 1,6-diphosphate (FDP), an intermediate product of glycolysis, regulates several enzymatic reactions in cells by activating phosphofructokinase, pyruvate kinase, and lactate dehydrogenase. The concentration of FDP in different cells is not the same, the concentration of FDP in human erythrocytes is 6-10mg / L cells. Biochemical studies in vivo and in vitro showed that pharmacological doses of FDP can act on cell membranes. Promote the uptake of potassium in the circulation by cells and stimulate the production of high-energy phosphoric acid and 2,3-bisphosphoglycerol in cells. In addition, FDP can reduce the hemolysis of red blood cells caused by mechanical trauma and inhibit the production of oxygen free radicals caused by chemical stimulation. [00...
