NCIt definition : The disodium salt form of cefotetan and a semi-synthetic, broad-spectrum, beta-lactamase-resistant,
second-generation cephalosporin antibiotic with bactericidal activity. Cefotetan disodium
causes inhibition of 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 the cell wall. This
results in a reduction of cell wall stability and causes cell lysis.;
