Chemical Formula


Iupac Name

(6R,7R)-3-{[(aminocarbonyl)oxy]methyl}-7-{[(2Z)-2-(2-furyl)-2-(methoxyimino) acetyl]amino}-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid


Cefuroxime is a parenteral second generation cephalosporin antibiotic. Cefuroxime axetil is an acetoxyetyl ester prodrug of cefuroxime which is effective orally. Used for the treatment of many different types of bacterial infections such as bronchitis, sinusitis, tonsillitis, ear infections, skin infections, gonorrhea, and urinary tract infections.

Adverse Effect

Large doses can cause cerebral irritation and convulsions; nausea, vomiting, diarrhoea, GI disturbances; erythema multiforme, Stevens-Johnson syndrome, epidermal necrolysis.

Potentially Fatal: Anaphylaxis, nephrotoxicity, pseudomembranous colitis.

Mechanism Action

Cefuroxime binds to one or more of the penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.


Caution should be exercised in patients with history of kidney or liver disease, colitis, or stomach problems, any allergy, who are taking other medications, elderly, children, during pregnancy and breast-feeding. 

Patient may experience with diarrhea, blood in stool or stomach pain; if it so consult with your doctor.

Drug Interaction

Probenecid decreases renal clearance of cefuroxime.

Potentially Fatal: Nephrotoxicity with aminoglycosides and furosemide.

Pregnancy Category

Category B: Either animal-reproduction studies have not demonstrated a foetal risk but there are no controlled studies in pregnant women or animal-reproduction studies have shown an adverse effect (other than a decrease in fertility) that was not confirmed in controlled studies in women in the 1sttrimester (and there is no evidence of a risk in later trimesters).


Absorbed from the GI tract with peak plasma concentrations after 2-3 hr (oral); may be enhanced by the presence of food.


Pleural and synovial fluid, sputum, bone and aqueous fluids; CSF (therapeutic concentrations). Crosses the placenta and enters breast milk. Protein-binding: Up to 50%.


The axetil moiety is metabolized to acetaldehyde and acetic acid.


Via the urine by glomerular filtration and renal tubular secretion (as unchanged); via bile (small amounts)
