Definitions

• the invention relates to a caloric nutrient solution free of free amino acids and their salts for parenteral, e.g. intravenous nutrition of humans with a content of at least one reducing sugar and a stabilizer for the sucker (s) and possibly other usual known energy sources.
• the invention relates to a multi-chamber system for parenteral nutrition of humans with a chamber containing an amino acid solution and a chamber containing a nutrient solution.
• amino acid pattern A wide variety of preparations and finished medicinal products for therapeutic and / or nutritional purposes have also been formulated for administration to patients with liver and kidney disease, with particular attention being paid to the amino acid pattern. It is known, for example from DE-OS 25 56 100, to administer the individual amino acids, namely essential as well as nonessential amino acids, in certain relative ratios to one another in the form of certain amino acid patterns.
• the amino acids are usually used as free amino acids.
• amino acid salts or amino acid derivatives For example, it is known to use the cysteine in the form of the hydrochloride or the N-acetyl derivative.
• amino acid solutions are impaired in their chemical stability by the heat load during heat sterilization. Furthermore, certain amino acids are sensitive to oxidation and their reaction products are able to react with unoxidized amino acids.
• DE-OS 38 14 806 by adding less than 0.5% cysteine, N-acetylcysteine or their salts and esters as antioxidants to amino acid solutions, the decomposition reactions caused by residual oxygen or oxygen diffused during storage are to be avoided.
• DE-OS 38 14 806 therefore recommends adding amino acid solutions N-acetylcysteine as an antioxidant.
• N-acetylcysteine-containing amino acid solutions with the entry of oxygen during storage have proven to be considerably more color-unstable than N-acetylcysteine-free amino acid solutions that N-acetylcysteine-free amino acid solutions, when mixed with solutions reducing sucker, show a discolouration within hours as a sign of rapid chemical reactions.
• the object of the invention is to provide amino acid solutions which are suitable for the parenteral and intravenous nutrition of humans and are packaged in a multi-chamber system or multiple container and which contain reducing sugar and which are characterized by optimal storage and color stability.
• N-acetylcysteine is no longer used as part of the amino acid solution, as is customary hitherto, but rather is added to the solution containing the reducing sugar or sugar.
• the invention thus relates to a caloric nutrient solution and a multi-chamber system as specified in the claims.
• N-acetylcysteine is excellently suitable for stabilizing solutions having a reducing action which are free from amino acids, but apart from one or more reducing actions, sugar and other energy sources which are customary for intravenous and parenteral nutrition in humans such as May contain polyols, for example xylitol and / or disaccharides, for example maltose, and / or fats and the like.
• the nutrient solution according to the invention can advantageously contain 0.01 to 50.0, preferably 0.05 to 5.0 g / l of N-acetylcysteine.
• Reducing sugars are all reducing sugars, especially pentoses and hexoses, which are suitable for parenteral and intravenous nutrition in humans.
• Glucose and fructose are preferably used.
• the solution can contain a sugar or a mixture of different sugars.
• the amino acid solutions can have one of the customary known amino acid patterns which are suitable for parenteral and intravenous nutrition in humans. Typical such patterns are e.g. known from DE-OS 25 56 100.
• the multi-chamber system or multiple container according to the invention can optionally have further chambers or containers which are filled with other substances which are necessary or advantageous for human nutrition, such as fats, Peptides, electrolytes and / or vitamins.
• the multiple chambers or multiple containers have the usual known structure. Accordingly, they exist in partially from liquid-tight plastic materials. However, the multiple containers can also consist of other materials, for example of glass.
• Zinc chloride 0.0082 made up to 1000 ml with water for injections 2.) in the second chamber a 40% glucose solution which had been mixed with 0.7 g / l N-acetylcysteine.
• the chamber system was subjected to a heat sterilization at 121 ° C. customary in pharmacopoeia.
• the sterilization time was 15 minutes.
