Cefepime is a fourth-generation cephalosporin with gram-positive and g
ram-negative activity, including anti-Pseudomonas activity. It is usef
ul in treating serious infections associated with Pseudomonas aerugino
sa, such as nosocomial pneumonias and infections in febrile leukopenic
compromised hosts. Because cefepime has low resistance potential and
is active against ceftazidime-resistant organisms, it is being used in
place of ceftazidime.
