Problems solved by technology

[0014] It is worth pointing out that the vast majority of compound amino acid injection manufacturers in my country do not yet have the process conditions and equipment for the whole production process of nitrogen protection. There are still uncertainties about whether the goal will be achieved

Abstract

The invention discloses a pharmaceutical composition containing 18 amino acids. The pharmaceutical composition is characterized in that a compound amino acid injection (18AA-V) with varied concentration is prepared by using the following components according to the following ratios of parts by weight: 2.89 of arginine hydrochloride, 2.46 of histidine hydrochloride, 3.79 of leucine, 1.70 of isoleucine, 3.33 of lysine hydrochloride, 2.83 of phenylalanine, 1.97 of threonine, 1.36 of valine, 1.06 of methionine, 0.39 of tryptophan, 3.24 of glycine, 1.88 of alanine, 1.00 of proline, 0.11 of tyrosine, 0.67 of serine, 0.44 of cysteine hydrochloride, 1.15 of aspartic acid, 1.97 of glutamic acid, 50 of xylitol, 0.10 to 0.30 of citric acid and injection water with proper amount. The pharmaceutical composition does not contain a sulfite antioxidant so that the pharmaceutical composition is clinically used in a safer manner. After an accelerated test and a quality test, results show that the pharmaceutical composition is as stable as or more stable than like products (18AA-V) which are sold in the markets and contain sulfites.

Description

technical field [0001] The invention belongs to the technical field of medicine, and more specifically relates to a pharmaceutical composition containing 18 kinds of amino acids and a preparation method thereof. Background technique [0002] The pharmaceutical composition containing 18 kinds of amino acids is a sterilized aqueous solution prepared from 18 kinds of amino acids plus auxiliary materials, and is clinically used for parenteral nutrition. [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 use in the 1960s, in order to ensure the stability of the product, sulfite compounds with unique antioxidant properties, such as sodium bisulfite and sodium metabisulfite, must be added. Since people did not understand the harm of such substances to the human body at that time, manufacturers usually added them in...
