Dextran 40 and Dextran 20, Dextran 70 Raw Material API for Injection BP, EP, USP CAS 9004-54-0 

Dextran is a white powder. Odorless and tasteless. It is soluble in hot water, insoluble in ethanol.Dextran is a polymer of several glucose molecules dehydrated, also called dextran, which is widely existed in microorganisms in nature, and it is an important part of the cell wall.Due to the large molecular weight, it can't be used directly for medicinal purposes, and it must be hydrolyzed into molecules of certain sizes to be used. The molecular weight of 25000～50000 is low molecular weight, 50000～9 0000 is medium molecular weight.
This product is a low molecular dextrose, mainly used as blood volume expanders, and its aqueous solution is a colloidal solution, which can maintain a good colloid osmotic pressure. Easily excreted from the kidney, half-life of only 3 hours. 10% solution of osmotic pressure than plasma protein is slightly higher than the liquid in the tissues can be absorbed into the blood, so it can quickly dilute the blood, reduce the erythrocyte ratio and plasma viscosity, and accelerate the blood flow, unclogging the microcirculation, which reduces the aggregation of erythrocytes in the blood vessels and platelet aggregation. It also prevents platelets from releasing factor III, and has a mild anticoagulant effect.
