Abstract

The invention relates to a high-concentration medium/long chained fat emulsion injection for injection. The technical proposal is that the components of the injection comprise 135-165g/l long chained triglyceride (soybean oil, for injection), 135-165g/l medium chained triglyceride (for injection), 11-14g/l lecithin (for injection), 15-25g/l glycerol (for injection), a right amount of sodium hydroxide or eunatrol, and the rest being water for injection. The manufacturing method of the medium/long chained fat emulsion is characterized in comprising steps of fat phase preparation, aqueous phase preparation, foremilk preparation, PH value adjustment, high-pressure homogenization, nitrogen-filled bulking and rotating sterilization. The high-concentration medium/long chained fat emulsion injection has the advantages that the invention provides the medium/long chained fat emulsion injection with safety, high energy, low capacity, isotonicity, low PL/TG ratio for patients; and the invention is suitable for the patients who cannot well utilize the long chained triglyceride due to the lack or inactivity of novain enzyme caused by pathological state and more suitable for the patients who need high energy but contemporarily need restriction on the liquid input.

Description

Technical field [0001] The invention relates to an injection and a manufacturing method thereof, in particular to a high-concentration medium / long-chain fat emulsion injection for injection and a manufacturing method thereof. Background technique [0002] Medium / long-chain fat emulsion injection is a new type of fat emulsion for parenteral nutrition, which is composed of medium-chain triglycerides and long-chain triglycerides in a ratio of 1:1. The medium-chain triglycerides in the formula provide suitable energy for human physiological metabolism, and the long-chain triglycerides provide the essential fatty acids needed by the human body, which can improve nitrogen balance, protect liver, lung and immune function, and have few side effects. The osmotic pressure of this product is basically the same as that of blood, and it can be infused through peripheral vein and central vein. It can be mixed with nutrients such as glucose, amino acids, electrolytes, vitamins and trace e...
