Embodiment 1

[0017] The prescription of reduced glutathione freeze-dried powder for injection consists of: (by weight)

[0018] Reduced Glutathione 900g

[0019] Sodium bicarbonate 120g

[0020] Appropriate amount of water for injection

[0021] Weigh 120g of sodium bicarbonate, stir and dissolve to make 15% sodium bicarbonate solution, and set aside; measure 70% of the prepared sodium bicarbonate solution, add it to 900g of reduced glutathione and stir, and use the remaining bicarbonate Add the sodium solution dropwise to make it fully dissolved, adjust the pH of the solution to 4.9-5.5, make up the water for injection to the full amount, stir evenly, add 0.03% activated carbon to stir, decarbonize and filter, and set aside; take the filtrate and fill it in a vial, freeze as follows Drying curve freeze-drying: when the shelf temperature of the freeze-drying machine drops to -10°C, put the filled qualified product on the shelf of the freeze-drying box, cool down at a rate of 30°C / h until...

Abstract

The invention provides a method for preparing injection reduced glutathione freeze-dried powder widely used for auxiliary treatment of multi-system or multi-organ diseases such as liver or kidney injury and diabetes. According to the method, reduced glutathione is used as an active ingredient and added with a pH regulator and injection water, and the injection reduced glutathione freeze-dried powder is prepared by freeze-drying. For overcoming the defects of the conventional technology for preparing the injection reduced glutathione freeze-dried powder, the invention provides the method for preparing the injection reduced glutathione freeze-dried powder. The reduced glutathione freeze-dried powder is prepared by strictly controlling formulation selection, solution preparation and freeze-drying processes; and although the method is long in freeze-drying time, the reduced glutathione freeze-dried powder prepared by the method is high in stability and has a good freeze-dried effect.

Description

Technical field: [0001] The invention relates to the field of pharmaceutical preparations, in particular to a preparation method of reduced glutathione freeze-dried powder for injection. Background technique: [0002] Reduced glutathione (GSH) is a tripeptide naturally synthesized in human cells. It is composed of glutamic acid, cysteine ​​and glycine, and contains sulfhydryl (-SH). It is widely distributed in various organs of the human body. It plays an important role in maintaining the biological functions of cells and protecting the integrity of cell membranes. As an important regulatory metabolic substance in cells, reduced glutathione is not only the prosthetic group of glyceraldehyde phosphate dehydrogenase, but also the coenzyme of glyoxalase and triose dehydrogenase, and participates in the tricarboxylic acid cycle in the body And sugar metabolism, and can activate a variety of enzymes, such as sulfhydryl (-SH) enzyme-coenzyme, etc., thereby promoting sugar, fat an...
