Embodiment 1

[0025] Take 12kg of reduced glutathione and 2kg of mannitol in a sterile container, add an appropriate amount of water for injection and stir to dissolve, adjust the pH value to 5.0-6.5 with 0.1mol / L sodium hydroxide, add water for injection to 40000ml, and test The intermediate is filtered with a 0.22 μm microporous membrane under sterile conditions, and the filtrate is divided into vials with 4ml each, and then the product is freeze-dried to obtain the product.

Embodiment 2

[0027] Take 6kg of reduced glutathione and 1.5kg of mannitol in a sterile container, add an appropriate amount of water for injection and stir to dissolve, adjust the pH value to 5.0-6.5 with 1M sodium carbonate solution, add water for injection to 20000ml, and detect the intermediate , filtered with a 0.22μm microporous membrane under sterile conditions, the filtrate was divided into vials, 2ml per bottle, and then the product was freeze-dried.

Embodiment 3

[0029] Put 18kg of reduced glutathione and 3.6kg of dextran in a sterile container, add an appropriate amount of water for injection and stir to dissolve, adjust the pH value to 5.0-6.5 with 0.1mol / L sodium hydroxide, add water for injection to 60000ml, Detect the intermediate, filter it with a 0.22 μm microporous membrane under sterile conditions, divide the filtrate into 6ml vials, and freeze-dry the product.

Abstract

The invention discloses a reduced-type glutathione freeze dried injection and making technique, which is characterized by the following: loading 95.0%-105.0% reduced-type glutathione (C10H17N3O6S) to display white block and powder; testing nitrosoferric sodium cyanide to display red; keeping the consistent reserving time of main peak of sample solution as comparison sample solution with pH value at 5.0-6.5; making dried weight not over 5.0% and the content of relative material not more than 4%; limiting the content of bacterial endotoxin less than 0.125EU; making other items satisfy the standard.

Description

technical field [0001] The invention relates to a glutathione freeze-dried powder injection and a preparation process thereof, in particular to a reduced glutathione freeze-dried powder injection and a preparation process thereof. Background technique [0002] Reduced glutathione (GSH) is a polypeptide naturally synthesized in human cytoplasm. It is composed of glutamic acid, cysteine ​​and glycine, and contains sulfhydryl (-SH). It is widely distributed in various organs of the body. important role in cell biological function. [0003] Reduced glutathione is mainly used clinically for chemotherapy patients and radiation therapy patients; various hypoxemias: such as acute anemia, adult respiratory distress syndrome, sepsis, etc.; liver diseases, including viral, drug toxicity, alcohol toxicity and other chemical substance toxicity caused by liver damage; can also be used for adjuvant treatment of organophosphorus, amine or nitro compound poisoning. [0004] At present, the...
