Administered parenterally, cefepime inhibits bacterial cell wall synthesis by binding to and inactivating penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity, resulting in a reduction of bacterial cell wall stability and cell lysis. This agent is more active against a variety of Gram-positive pathogens compared to third-generation cephalosporins."}]
