From the Guidelines

Cefuroxime is a second-generation cephalosporin antibiotic. It belongs to the beta-lactam class of antibiotics and has an expanded spectrum of activity compared to first-generation cephalosporins, as noted in the study published in the Journal of Allergy and Clinical Immunology 1. Some key points about cefuroxime include:

  • It is effective against many gram-positive bacteria and has improved activity against gram-negative organisms, including Haemophilus influenzae, Moraxella catarrhalis, and some Enterobacteriaceae.
  • It is commonly used to treat various infections including respiratory tract infections, otitis media, sinusitis, urinary tract infections, and skin infections.
  • Cefuroxime is available in both oral form (cefuroxime axetil) and injectable form (cefuroxime sodium), with the oral form typically coming in 250mg and 500mg tablets.
  • The mechanism of action of cefuroxime involves inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins, which leads to bacterial cell death, and it has greater stability against beta-lactamase enzymes produced by certain bacteria, giving it a broader spectrum of activity compared to first-generation cephalosporins, as discussed in the context of treating acute bacterial sinusitis 1.

From the Research

Cefuroxime Generation

  • Cefuroxime is classified as a second-generation cephalosporin 2, 3, 4, 5, 6.

Characteristics of Second-Generation Cephalosporins

  • Second-generation cephalosporins have a broad spectrum of activity against both Gram-positive and Gram-negative organisms 2.
  • They are relatively stable against beta-lactamase hydrolysis, which makes them effective against bacteria that produce beta-lactamases 3, 5.

Comparison with Other Cephalosporins

  • Cefuroxime has a similar spectrum of activity to cefamandole, another second-generation cephalosporin 3.
  • It is more active against beta-lactamase-producing Haemophilus influenzae than other second-generation cephalosporins 6.
