Problems solved by technology

Intravenous injection is a 100% method to effectively inject GSH into the blood, but GSH intravenous injection has the following disadvantages: 1. Inconvenient use and painful injection; 2. Cannot be injected every day; 3. The half-life of GSH in the blood after injection is relatively short , about 7~10min
Oral dosage forms such as capsules and tablets are convenient to use, but the bioavailability of GSH is low

Abstract

The invention relates to a reduced glutathione percutaneous absorption preparation and a preparation method thereof, and belongs to the field of medicinal preparations. In the technical problem, the invention provides a reduced glutathione percutaneous absorption preparation which has the sustained-release effect. The reduced glutathione percutaneous absorption preparation is prepared from an auxiliary material bag and reduced glutathione, wherein an auxiliary material is at least one of gamma-cyclodextrin, a derivative of the gamma-cyclodextrin, alpha-cyclodextrin and a derivative of the alpha-cyclodextrin. The reduced glutathione percutaneous absorption preparation has the advantages of quick response, long half-life period and high bioavailability, is convenient to use and does not have pain. The reduced glutathione provides a new preparation, and has a wide application prospect.

Description

technical field [0001] The invention relates to a reduced glutathione percutaneous absorption preparation and a preparation method thereof, belonging to the field of pharmaceutical preparations. Background technique [0002] Reduced glutathione (GSH) is a peptide naturally synthesized in human cytoplasm, composed of glutamic acid, cysteine ​​and glycine, containing thiol (-SH), widely distributed in various cells of the body, especially in Liver, kidney, and red blood cells are more widely distributed. There are mainly two types of glutathione in the human body: reduced (GSH) and oxidized (GSSG), and the ratio of the two is about 100:1. GSH is the prosthetic group of glyceraldehyde phosphate dehydrogenase, and the coenzyme of glyoxalase and triose dehydrogenase, and participates in the tricarboxylic acid cycle and glucose metabolism in the body. GSH has a wide range of clinical applications, such as: GSH can be directly used for liver damage, viral hepatitis, fatty liver, ...
