Pharmacology
Cefuroxime is a β-lactam type antibiotic. More specifically, it is a second-generation cephalosporin. Cephalosporins work the same way as penicillins: they interfere with the peptidoglycan synthesis of the bacterial wall by inhibiting the final transpeptidation needed for the cross-links. This effect is bactericidal. Cefuroxime is effective against the following organisms: Aerobic Gram-positive Microorganisms: Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes. Aerobic Gram-negative Microorganisms: Escherichia coli, Haemophilus influenzae (including beta-lactamase-producing strains), Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis (including beta-lactamase-producing strains), Neisseria gonorrhoeae (including beta-lactamase-producing strains). Spirochetes: Borrelia burgdorferi.

Patient Information
Patients should be counseled that antibacterial drugs including Cefuroxime for Injection USP and Dextrose
Injection USP should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common
cold). When Cefuroxime for Injection USP and Dextrose Injection USP is prescribed to treat a bacterial infection,
patients should be told that although it is common to feel better early in the course of therapy, the medication
should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the
effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and
will not be treatable by Cefuroxime for Injection USP and Dextrose Injection USP or other antibacterial drugs in the
future.
