Cefuroxime Sodium is a broad-spectrum, semi-synthetic second-generation cephalosporin antibiotic with increased stability to beta-lactamases.  It is bactericidal against Gram-negative and Gram-positive bacteria.  Cefuroxime sodium is freely soluble in aqueous solution (0.145 mg/mL).

    Mechanism of Action

    Like β-lactams, cephalosporins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to cephalosporins is commonly due to cells containing plasmid encoded β-lactamases. Like many second generation cephalosporins, Cefuroxime is relatively stable in the presence of β-lactamases.

    Tariff Code



    Cefuroxime sodium is a broad-spectrum antibiotic targeting a wide variety of Gram-negative and Gram-positive bacteria.


    Eukaryotic Cell Culture Applications

    Rat erythrocyte glucose-6-phosphate dehydrogenase was found to increase in activity in response to Cefuroxime exposure in vitro (Temel Y et al, 2018). 

    Cell proliferation, cytotoxicity, cell metabolism, and extracellular matrix calcification were assessed after antibiotic treatment. Cefuroxime had no inhibiting effects on osteoblasts with lower concentrations (25-100 ug/ml), but higher concentrations (250-1000 ug/ml) saw an increase in cell proliferation and cytotoxicity, and an inhibition of cell metabolism (Salzmann GM et al, 2007).

    Microbiology Applications

    Cefuroxime sodium is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram-positive and Gram-negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Representative MIC values include:

    • Haemophilus influenzae 0.25 µg/mL – 4 µg/mL
    • Neisseria gonorrhoeae 0.2 µg/mL – 1.6 µg/mL
