Problems solved by technology

That is to say, if supplementary materials such as mannitol and tert-butanol are added in the production of reduced glutathione freeze-dried powder injection, relevant regulations must be complied with, corresponding safety tests, stability tests, etc. should be carried out and reported to the relevant national authorities. It can only be implemented after approval by the department, and tert-butanol does not belong to the pharmaceutical excipients stipulated in the Pharmacopoeia, and it is difficult to guarantee the freeze-drying residue, and there is a large risk of use

Abstract

The invention relates to a reduced glutathione for injection and a pre-freezing method thereof. The pre-freezing method includes the following steps that S1, a glutathione solution is prepared and filled; S2, the partition plate temperature of a freeze-drying machine is reduced to be -25 to -35 DEG C; S3, the filled glutathione solution in the step S1 is put on a partition plate of the freeze-drying machine after the step S2 is completed, constant temperature is kept for 2 to 6 hours after the temperature of a product is reduced to be -25 to -35 DEG C, and a reduced glutathione frozen body is obtained, wherein a vacuum pump is started within 0.5 to 1 hour before constant temperature completion in the step S3 to enable the vacuum degree to be smaller than 10 Pa. The reduced glutathione used for injection and prepared by means of the pre-freezing method has the advantages of being high in safety, simple in freeze-drying operation, good in resolubility and stable and reliable in product quality.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to reduced glutathione for injection and a prefreezing method thereof. Background technique [0002] Reduced glutathione (GSH) is a polypeptide naturally synthesized in human cytoplasm, composed of glutamic acid, cysteine ​​and glycine, containing thiol (-SH), widely distributed in various organs of the body, is a biochemical An important antioxidant component of the system, which plays an important role in liver biochemical metabolism. Clinically, it has detoxification and anti-oxidation effects, and is mainly used for the prevention and treatment of chemotherapy and drug-induced liver injury in cancer patients, and the treatment of various hepatitis. Reduced glutathione is sensitive to heat due to the presence of active sulfhydryl groups, and is easily oxidized. It is unstable in aqueous solution and has a high viscosity. It is difficult to sublimate water in the produc...
