Abstract

The invention discloses a medicine combination which contains 15 amino acids and the preparation method thereof; the medicine combination is characterized in that a compound amino acid injecta with different concentrations are prepared by the 15 amino acids which serve as raw materials and admixture according to the following parts by weight: 6.1-10.8 parts of L-Isoleucine, 8.8-16.6 parts of L-Leucine, 4.6-10.4 parts of L-Lysine Acetate, 0.8-3.0 parts of L-Methionine, 0.8-3.9 parts of L-Phenylalanine, 1.6-5.4 parts of L-threonine, 0.5-1.1 parts of L-Tryptophan, 6.7-10.7 parts of L-Valine, 3.2-9.3 parts of L-alanine, 4.6-7.2 parts of L-arginine, 1.2-2.9 parts of L-Histidine, 5.0-9.6 parts of L-proline, 2.6-6.0 parts of L-serine, 2.6-10.8 parts of glycin, 0.1-1.0 parts of L-Cysteine hydrochloride, 0.1-0.5 parts of citric acid and moderate water for injection. The injecta does not contain sulphite type chemical inhibitor, thoroughly solves the harm of sulphite type on human body, and ensures that the obtained products are safer. The PH value of the injecta is 5.5-7.0. By the accelerated test and quality test, the results show that the stability of the medicine combination which contains 15 amino acids is the same as or better than like products which contains sulphite type sold on market.

Description

technical field [0001] The invention belongs to the technical field of medicine, and more specifically relates to a pharmaceutical composition containing 15 kinds of amino acids and a preparation method thereof. Background technique [0002] The pharmaceutical composition containing 15 kinds of amino acids is a sterilized aqueous solution prepared from 15 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...
