Alcohol in Dextrose Injection
»Alcohol in Dextrose Injection is a sterile solution of Alcohol and Dextrose in Water for Injection.It contains not less than 90.0percent and not more than 110.0percent of the labeled amount of alcohol (C2H5OH),and not less than 95.0percent and not more than 105.0percent of the labeled amount of dextrose (C6H12O6·H2O).
Packaging and storage
Preserve in tight,single-dose containers,preferably of Type Ior Type IIglass,and store at controlled room temperature.
Labeling
The label states the total osmolarity of the solution expressed in mOsmol per liter.
Identification
It responds to the Identificationtests under Dextroseand under Dehydrated Alcohol.
Bacterial endotoxins á85ñ
It contains not more than 0.5USP Endotoxin Unit per mL.
pHá791ñ:
between 3.5and 6.5,determined on a portion to which 0.30mLof saturated potassium chloride solution has been added for each 100mLand which previously has been diluted with water,if necessary,to a concentration of not more than 5%of dextrose.
Heavy metals á231ñ
Transfer a volume of Injection,equivalent to 4.0g of dextrose,to a vessel,and adjust the volume to 25mLby evaporation or by addition of water,as necessary:the limit is 0.0005C%,in which Cis the labeled amount,in g,of C6H12O6·H2Oper mLof Injection.
Limit of 5-hydroxymethylfurfural and related substances
Dilute an accurately measured volume of Injection,equivalent to 1.0g of C6H12O6·H2O,with water to 500.0mL.Determine the absorbance of this solution in a 1-cm cell at 284nm,with a suitable spectrophotometer,using water as the blank:the absorbance is not more than 0.25.
Other requirements
It meets the requirements under Injections á1ñ.
Assay for alcohol
Determine by the Distillation Method á611ñ,using a 50.0-mLportion of Injection.
Assay for dextrose
Transfer an accurately measured volume of Injection,containing from 2g to 5g of dextrose,to a 100-mLvolumetric flask.Add 0.2mLof 6Nammonium hydroxide,dilute with water to volume,and mix.Determine the angular rotation in a 200-mm tube at 25(see Optical Rotation á781ñ).The observed rotation in degrees,multiplied by 1.0425,represents the weight,in g,of C6H12O6·H2Oin the volume of Injection taken.
