Abstract

The invention discloses an amino acid composition containing a new antioxidant. The compound amino acid injection (18AA-VII) with different concentrations is characterized by being prepared from 9.10 g of isoleucine, 12.9 g of leucine, 10.00 g of lysine acetate, 4.40 g of methionine, 7.00 g of phenylalanine, 7.5 g of threonine, 1.30 g of tryptophan, 14.00 g of valine, 7.10 g of alanine, 9.00 g of arginine, 1.00 g of aspartic acid, 0.50 g of glutamic acid, 5.00 g of histidine, 5.00 g of proline, 1.70 g of serine, 0.40 g of tyrosine, 7.00 g of glycine 0.35 g of cysteine, 0.20-0.30 g of citric acid and a proper amount of pH regulator. The composition does not contain sulfite antioxidants, the harm of sulfites to human bodies is solved, and thus, the product becomes safer in clinic use. Detection results of accelerated tests show that the stability of the compound amino acid injection is better than or the same to that of like products.

Description

technical field

[0001] The invention belongs to the technical field of medicine, and more specifically relates to an amino acid composition containing a novel antioxidant and a preparation method thereof. Background technique

[0002] Compound Amino Acid Injection (18AA-VII) is a sterilized aqueous solution prepared from 18 kinds of amino acids plus excipients. It is clinically used as an amino acid supplement, which can regulate nitrogen balance and promote protein synthesis and wound healing.

[0003] Since amino acids are very unstable in solution, they are easily oxidized to produce a series of complex substances harmful to the human body. Since the compound amino acid injection was put into production and application in the 1960s, in order to ensure the stability of the product, sulfite compounds with unique antioxidant effects, such as sodium bisulfite and sodium metabisulfite, must be added.

[0004] So far, among the compound amino acid injection drugs that have bee...
