Embodiment 1

[0029] Take 1.6kg of sodium hydroxide, add appropriate amount of cooling water for injection to prepare sodium hydroxide solution. Take an appropriate amount of water for injection, cool it down, inject sterile nitrogen gas for 15-20 minutes, and then add 12kg of glutathione to make a suspension. Under the condition that both the sodium hydroxide solution and the suspension are fed with sterile nitrogen and airtight, the sodium hydroxide solution is slowly added to the glutathione suspension, and the pH value of the solution is adjusted to 5.2-5.4. Add water for injection to the full amount, continue to pass in sterile nitrogen, stir evenly, and filter aseptically. Fill into shallow freeze-drying trays, fill each tray with 7kg, first keep at -20°C for 3 hours, then rise to -5°C within 2 hours, keep at -5°C for 1 hour, and then drop to - within 1.5 hours Keep it at 42°C for 2 hours, vacuumize, raise the temperature to 50-53°C, keep it warm for 13-14 hours, after freeze-drying ...

Abstract

Production of injection reducing glutathione is carried out by pre-freezing for reducing glutathione solution and freeze-drying. It's simple, cheap, has stable product quality and less water content and related substances and can be used for industrial production.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a method for preparing reduced glutathione for injection. Background technique [0002] Glutathione is widely distributed in the cells of mammals, plants and microorganisms. It is the most important and abundant low-molecular-weight active peptide containing sulfhydryl groups. It is an important antioxidant component in the biochemical system and plays an important role in the biochemical metabolism of the liver. Clinically, it is mainly used as a drug for detoxification and anti-oxidation, to prevent and treat chemotherapy and drug-induced liver damage in cancer patients, to treat chronic fatty liver, to treat viral hepatitis and cirrhosis, etc. [0003] Reduced glutathione is sensitive to heat, is unstable in aqueous solution, has high viscosity, and is easily oxidized. All of the above situations can easily cause the increase of related substances. Therefore, a stab...
