Cefazolin for Injection USP and Dextrose Injection USP is a sterile, nonpyrogenic, single-dose, 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 semi-synthetic 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-(1 H -tetrazol-1-yl)acetamido]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate. Its empirical formula is C 14 H 13 N 8 NaO 4 S 3 and its molecular weight is 476.48. 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. Its empirical formula is C 6 H 12 O 6 •H 2 O and its molecular weight is 198.17. Hydrous Dextrose USP has the following structural (molecular) formula: Cefazolin Sodium USP is supplied as a lyophilized form equivalent to either 1 gram, 2 grams or 3 grams of cefazolin. The 1 gram / container Cefazolin Sodium USP contains 1 gram of cefazolin (equivalent to 1.048 grams of cefazolin sodium). The 2 grams / container Cefazolin Sodium USP contains 2 grams of cefazolin (equivalent to 2.096 grams of cefazolin sodium). The 3 grams / container Cefazolin Sodium USP contains 3 grams of cefazolin (equivalent to 3.145 grams of cefazolin sodium). Dextrose Hydrous USP has been added to the diluent (Water for Injection USP) to adjust osmolality (approximately 2 grams [4% w/v], 1.5 grams [3% w/v] and 1 gram [2% w/v] for the 1 gram, 2 gram or 3 gram dosages, respectively). After removing the peelable foil strip, activating the seals, and thoroughly mixing, the reconstituted drug product is intended for single intravenous use. The pH of reconstituted solutions of Cefazolin for Injection and Dextrose Injection is 3.5 to 7.0. Reconstituted solutions of Cefazolin for Injection and Dextrose Injection range in color from pale yellow to amber. Not made with natural rubber latex, PVC or DEHP. 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. Cefazolin Sodium USP has the following structural formula Hydrous Dextrose USP has the following structural (molecular) formula
