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.

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

Excretion: Via the urine by glomerular filtration and renal tubular secretion (as unchanged); via bile (small amounts); 70 min (elimination half-life); prolonged in neonates and renal impairment.
