Abstract
The invention provides an ethoxyl starch 130 / 0.4 sodium chloride injection, in which, 20-80g of ethoxyl starch 130 / 0.4 and 5-13g of sodium chloride is include in per litre injection. The invention further provides the preparing method and application of the injection. The ethoxyl starch 130 / 0.4 in the raw material of the medicine in the invention is an improved product of 'heas' used clinically for treating and preventing hypovolemia, acute normovolemic hemodilution and so on. A better normovolemic therapeutic effect is achieved by optimizing molecular weight and molecular weight distribution, reducing displacement grade and changing displacement manner (C2 / C6); it can stays in blood for longer time after intravenous drip, consequently, can increase plasma osmotic pressure, tissue fluid back-flow and blood volume, can improve oxygenation condition in or after major operation evidently, and can increase tissue oxygen partial pressure and improve tissue oxygenation faster and earlier, thereby can satisfy the clinic demand better.
Description
technical field [0001] The invention relates to hydroxyethyl starch 130 / 0.4 sodium chloride injection, belonging to the pharmaceutical field. Background technique [0002] As a blood volume expansion drug, artificial colloid plays an extremely important role in the treatment and prevention of hypovolemia and shock. Compared with blood plasma, albumin and crystalloid, artificial colloid has the advantages of low cost and long action time as blood volume expansion drug, and can effectively avoid the occurrence of infectious diseases caused by the use of blood products. The hydroxyethyl starch solution made of corn starch is the third generation artificial colloid after gelatin and dextran colloids. Since it was introduced into clinical practice in 1962, after more than 30 years, due to continuous replacement and renewal, it has gradually become the most popular in European and American countries. A popular plasma expander with broad market prospects. [0003] At present, hy...
