NCIt definition : The sodium salt form of cefoperazone and a semi-synthetic, broad-spectrum, beta-lactamase
resistant, third-generation cephalosporin antibiotic with bactericidal activity. Cefoperazone
sodium inhibits bacterial cell wall synthesis by inactivating penicillin binding proteins
(PBPs) thereby interfering with the final transpeptidation step required for cross-linking
of peptidoglycan units which are a component of bacterial cell walls. This results
in a reduction of cell wall stability and causes cell lysis.;
