Problems solved by technology

[0004] The Chinese patent "200610091185.7 A pharmaceutical composition for expanding blood volume and its preparation method" mentions that the pharmaceutical composition does not contain calcium, but the prescription contains magnesium ions. The reason is that it is not the case in clinical use due to incompatibility. , because the range of incompatibility between magnesium and calcium ions and other drugs is roughly the same, the incompatibility problems encountered by calcium ions, magnesium ions will also encounter

Abstract

The invention provides a pharmaceutical composition for expanding blood volume. The composition contains hydroxyethyl group starch and an electrolyte component. Content of components in the pharmaceutical composition is as follows: 55-65g / L of hydroxyethyl group starch 200 / 0.5, 120-145mmol / L of sodion, 3.5-5.5mmol / L of potassium ion, 1.0-3.5mmol / L of calcium ion, 96-125mmol / L of chloridion and 27-50mmol / L of acetate ion, and the pharmaceutical composition contains 0.7-1.25mmol / L of magnesian ion or does not contain the magnesian ion and contains 0.99g / L of glucose does not contain the glucose. The hydroxyethyl group starch is the hydroxyethyl group starch 200 / 0.5, the weight-average molecular weight of the hydroxyethyl group starch 200 / 0.5 ranges from 175,000 dalton to 225,000 dalton, and the mol substituted ratio of the hydroxyethyl group starch 200 / 0.5 ranges from 0.43 to 0.55.

Description

technical field [0001] The invention relates to a pharmaceutical composition, in particular to a pharmaceutical composition containing hydroxyethyl starch 200 / 0.5 and electrolyte balance liquid, and belongs to the field of pharmaceutical preparations. Background technique [0002] Hypovolemia is a common problem in surgical patients during the perioperative period, so it is very important to choose the appropriate type of fluid for safe and effective volume therapy. Crystalloids, colloids, and whole blood are used clinically for volume supplementation. In recent years, artificial colloids have been widely used. The commonly used ones are dextran, hydroxyethyl starch, gelatin, etc. In recent years, due to the expansion effect and safety of hydroxyethyl starch, it is the most ideal among various artificial colloids, and it has gradually become the most ideal. Widely used plasma expander. my country began to use hydroxyethyl starch 706 generation plasma (HES40 / 0.9) in the 197...
