Problems solved by technology

According to the report of Holm et al., compared with the infusion containing only BCAA, the infusion containing BCAA and a small amount of phenylalanine, tryptophan and methionine has a more obvious correction effect on the patient's amino acid level and can achieve positive nitrogen balance; 80g amino acid / Postoperative patients in the daily dose group achieved nitrogen balance within 2 weeks, while postoperative patients in the 50g amino acid / day dose group could not achieve nitrogen balance

Abstract

The present invention comprises a compound amino acid injection and the preparation method. The characteristics of the injection are as follows. The prescription comprises most human essential amino acid and non essential amino acid. Content of branched chain amino acid (BCAA) in each amino acid is high, and content of the aromatic amino acid (AAA) is low. Content of arginine is high. The prescription comprises the acetylcysteine. The compound amino acid injection is prepared under strict control of aerobic environment, which makes the product in accordance with quality requirement without any antioxidant. The production is applicable in the patients with hepatic disease, which is in accordance with specific requirement for AAA restriction. No antioxidant is added in the prescription, which can effectively reduce incidence rate of adverse reaction in clinical application.

Description

technical field [0001] The invention discloses a compound amino acid injection composition containing 15 kinds of amino acids and a preparation method thereof. The prescription of the compound amino acid injection composition is suitable for liver disease patients. Background technique [0002] Malnutrition is a recurring problem in patients with chronic liver disease. Malnutrition is very common in patients with chronic liver disease due to the reduction of dietary protein intake in patients with chronic liver disease, and chronic liver disease itself is a chronic wasting disease and can cause nutritional metabolism disorders in patients. Among the malnutrition that occurs, "protein-energy malnutrition (PEM)" is the most common type. The survey found that the incidence of PEM in patients with liver cirrhosis is as high as 20-60%. [0003] Malnutrition is very common in patients with chronic liver disease, and it is closely related to liver dysfunction, attack rate and mor...
