Dextran 40 And Dextrose Injection

Product Description

Dextran 40) is a sterile, nonpyrogenic preparation of low molecular weight dextran (average mol. wt. 40,000) in 5% Dextrose Injection or 0.9% Sodium Chloride Injection. It is administered by intravenous infusion. Also described as low viscous or low viscosity dextran, dextran 40 is prepared by acid hydrolysis and differential fractionation of a crude macromolecular polysaccharide produced from the fermentation.

Also described as low viscous or low viscosity dextran, dextran 40 is prepared by acid hydrolysis and differential fractionation of a crude macromolecular polysaccharide produced from the fermentation of sucrose by the bacterium, Leuconostoc mesenteroides (strain B-512). The crude material is composed of linked glucose units. In the fraction represented by dextran 40, 80% of the molecules have a molecular weight ranging from 10,000 to 90,000 (average approximately 40,000) when measured by a light scattering method.

More than 90% of the linkages are of the 1,6 alpha glucosidic, straight chain type.Each 100 mL of 10% LMD (dextran 40) in 5% Dextrose Injection contains 10 g dextran 40 and 5 g dextrose hydrous in water for injection. Total osmolar concentration is 255 mOsmol/liter (calc.); pH is 4.4 (3.0 to 7.0).Each 100 mL of 10% LMD (dextran 40) in 0.9% Sodium Chloride Injection contains 10 g dextran 40 and 0.9 g sodium chloride in water for injection. Total osmolar concentration is 310 mOsmol/liter (calc.); pH is 4.9 (3.5 to 7.0) (may contain sodium hydroxide and/or hydrochloric acid for pH adjustment). Electrolyte concentration per liter: Na+ 154 mEq; Cl- 154 mEq (not including ions for pH adjustment).The solutions contain no bacteriostat, antimicrobial agent or added buffers (except for pH adjustment) and are intended only for single-dose injection. When smaller doses are required the unused portion should be discarded.10% LMD (dextran 40) is an artificial colloid harmacologically classified as a plasma volume expander; 5% Dextrose Injection is a fluid and nutrient replenisher; 0.9% Sodium Chloride Injection is a fluid and electrolyte replenisher.Dextran 40 is a linear glucose polymer (polysaccharide) chemically designated (C6 H10 O5)n.
