What is Zinacef?
Zinacef is a prescription medicine that is used to treat or prevent bacterial infections.
Cefuroxime (cefuroxime (cefuroxime injection) injection) for Injection USP and Dextrose Injection USP is a sterile, nonpyrogenic, single use, packaged combination of Cefuroxime Sodium USP (crystalline) and Dextrose Injection USP (diluent) in the DUPLEX sterile container. The DUPLEX Container is a flexible dual chamber container.
The drug chamber is filled with sterile crystalline Cefuroxime (cefuroxime (cefuroxime injection) injection) for Injection USP, a semisynthetic, broad-spectrum, cephalosporin antibiotic for parenteral administration. It is the sodium salt of (6R,7R)-7-[2-(2-furyl)glyoxylamido]-3-(hydroxymethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate, 72-(Z)-(O-methyloxime), carbamate (ester).
Cefuroxime (cefuroxime (cefuroxime injection) injection) Sodium USP has the following structural formula:
The empirical formula is C16H15N4NaO8S, representing a molecular weight of 446.4.
Cefuroxime (cefuroxime (cefuroxime injection) injection) contains approximately 54.2 mg (2.4 mEq) of sodium per gram of cefuroxime (cefuroxime (cefuroxime injection) injection) activity.
The diluent chamber contains Dextrose Injection USP. The concentration of Hydrous Dextrose USP has been adjusted to render the reconstituted drug product iso-osmotic. 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.
Dextrose hydrous USP has been added to the diluent to adjust osmolality (approximately 1.45 g and 2.05 g to 750 mg and 1.5 g dosages, respectively).
After removing the peelable foil strip, activating the seals, and thoroughly mixing, the reconstituted drug product is intended for single intravenous use. When reconstituted, the approximate osmolality of the reconstituted solution for Cefuroxime (cefuroxime (cefuroxime injection) injection) for Injection USP and Dextrose Injection USP is 290 mOsmol/kg.
The DUPLEX Container is Latex-free, PVC-free, and Di (2-ethylhexyl) phthalate (DEHP)-free.
