Cefuroxime is a bactericidal second generation cephalosporin antibiotic which is active against a wide range of Gram-positive and Gram-negative susceptible organisms including many beta-lactamase producing strains. Cefuroxime inhibits bacterial cell wall synthesis by interfering with the transpeptidation process.
Clavulanic acid is a naturally derived beta lactamase inhibitor produced by Streptomyces clavuligerus. It has similar structure to beta lactam antibiotics which binds irreversibly to beta-lactamase enzymes and inactivates them. Clavulanic acid gives protection of Cefuroxime from degradation by beta lactamase enzymes and provides a solution for the treatment of bacterial infections caused by beta lactam resistant bacteria.
It is indicated for the treatment of infections caused by sensitive bacteria.
- Pharyngitis/Tonsillitis caused by Streptococcus pyogenes.
- Acute Bacterial Otitis Media caused by Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis (beta-lactamase producing strains) or Streptococcus pyogenes.
- Acute bacterial maxillary sinusitis caused by Streptococcus pneumoniae or Haemophilus influenzae (non beta-lactamase producing strains)
- Lower respiratory tract infections including pneumoniae, caused by Streptococcus pneumoniae, Haemophilus influenzae (including beta lactamase-producing strains), Klebsiella spp., Staphylococcus aureus (penicillinase- and non-penicillinase-producing strains), Streptococcus pyogenes, E. coli.
- Acute bacterial exacerbation of chronic bronchitis and secondary bacterial infections of Acute bronchitis caused by Streptococcus pneumoniae, Haemophilus influenzae (beta-lactamase negative strains) or Haemophilus parainfluenzae (beta-lactamase negative strains).
- Uncomplicated skin and skin-structure infections caused by Staphylococcus aureus (including beta-lactamase producing strains) or Streptococcus pyogenes.
- Uncomplicated urinary tract infections caused by E.coli or Klebsiella pneumoniae.
- Bone and Joint Infections caused by Staphylococcus aureus (penicillinase- and non-penicillinase-producing strains).
- Uncomplicated Gonorrhoea caused by penicillinase-producing and non-penicillinase producing strains of Neisseria gonorrhoeae.
- Early Lyme Disease (erythema migrans) caused by Borrelia burgdorferi.
- Septicemia caused by Staphylococcus aureus, Streptococcus pneumoniae, E.coli, Haemophilus influenzae (including ampicillin-resistant strains) & Klebsiella spp.

Cefuroxime-Clavulanic Acid is contraindicated in patients with known allergy to cephalosporin & in patients with Pseudomembranous Colitis.
Generally Cefuroxime-Clavulanic Acid is well tolerated. However, a few side effects like nausea, vomiting, diarrhea, abdominal discomfort or pain may occur. As with other broad-spectrum antibiotics, prolonged administration of Cefuroxime and Clavulanic acid combination may result in overgrowth of nonsusceptible microorganisms. Rarely (<0.2%) renal dysfunction, anaphylaxis, angioedema, pruritis, rash and serum sickness like urticaria may appear.
Cefuroxime should be given with care to patients receiving concurrent treatment with potent diuretics & who has history of colitis.
Pregnancy & Lactation
While all antibiotics should be avoided in the first trimester if possible. However, Cefuroxime-Clavulanic Acid can be safely used in later pregnancy to treat urinary and other infections. Cefuroxime-Clavulanic Acid is excreted into the breast milk in small quantities. However, the possibility of sensitizing the infant should be kept in mind.
