Hydroxyethyl starch(HES)200/0.5 APIs, formed by acid-hydrolyzed and hydroxyethylized high branched chain amylopectin starch, is a medium MW and low molar substitution ratio HES. Its chemical formula is poly (O-2-hydroxyethyl) starch, and the common name is HES200/0.5 (Penta starch). HES solution has quick effect and strong volume expansion properties; it can maintain four hours' middle strength expansion; it can be cleared away from kidney; less accumulation in plasma and tissue, least effect on coagulation; it can improve microcirculation. HES 200/0.5 solution is the most frequently used plasma substitute in Europe, and is the preferred remedy in curing and defending hypovolemia and shock. * HES 200/0.5 API & SolutionAbout HES.rar* Export Quality Standard
