Cefazolin for Injection USP and Dextrose Injection USP (cefazolin and dextrose for injection) is a sterile, nonpyrogenic, single use, packaged combination of Cefazolin Sodium USP (lyophilized) and sterile iso-osmotic diluent in the DUPLEX sterile container. The DUPLEX Container is a flexible dual chamber container.
After reconstitution the approximate osmolality for Cefazolin for Injection USP and Dextrose Injection USP is 290 mOsmol/kg.
The drug chamber is filled with sterile lyophilized Cefazolin Sodium USP, a
semisynthetic cephalosporin and has the following IUPAC nomenclature: Sodium
(6R, 7R)-3-[[(5-methyl-1,3,4-thiadiazol-2-yl)thio]methyl]-8-oxo-7-[2-(1H-tetrazol-1-yl)acetamido]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate.
Cefazolin Sodium USP has the following structural formula:
The sodium content is 48 mg/g of cefazolin sodium.
The diluent chamber contains Dextrose Injection USP, an iso-osmotic diluent using Hydrous Dextrose USP in Water for Injection USP. Dextrose Injection USP is sterile, nonpyrogenic, and contains no bacteriostatic or antimicrobial agents. Hydrous Dextrose USP has the following structural (molecular) formula:
The molecular weight of Hydrous Dextrose USP is 198.17
Cefazolin Sodium USP is supplied as a lyophilized form equivalent to 1 g of
cefazolin. Dextrose hydrous USP has been added to the diluent to adjust osmolality
(approximately 2 g).
After removing the peelable foil strip, activating the seals, and thoroughly
mixing, the reconstituted drug product is intended for single intravenous use.
The DUPLEX Container is Latex-free, PVC-free, and Di (2-ethylhexyl) phthalate
(DEHP)-free.
The DUPLEX dual chamber container is made from a specially formulated material.
The product (diluent and drug) contact layer is a mixture of thermoplastic rubber
and a polypropylene ethylene copolymer that contains no plasticizers. The safety
of the container system is supported by USP biological evaluation procedures.
