The bactericidal activity of cefotetan disodium is caused by an inhibition of bacterial cell wall synthesis via inhibition of cross-linking of peptidoglycans. This results in a reduction of cell wall stability and causes cell lysis. Cefotetan disodium is more active against gram-negative organisms and less active against gram-positive organisms compared to first-generation cephalosporins."}]
