Cefepime is a broad-spectrum, bactericidal antibiotic that works by inhibiting bacterial cell wall synthesis, leading to bacterial death. It is effective against a wide range of Gram-positive and Gram-negative bacteria, including strains resistant to other cephalosporins.

Cefepime has enhanced stability against beta-lactamases, making it useful in treating serious infections caused by resistant bacteria. The injection comes as a sterile powder that must be reconstituted with a suitable diluent before intravenous (IV) or intramuscular (IM) administration.
