Cefepime is a fourth generation cephalosporin antibiotic that was developed in 1994. It has more activity than third generation cephalosporins against Gram positive and Gram negative bacteria, and because of this, its use is typically reserved for severe nococomial pneumonia, infections of a multi resistant bacterial strain and the treatment of febrile neutropenia. It is indicated for the treatment of pneumonia caused by Streptococcus pneumoniae, Pseudomonas aeruginosa, Klebsiella pneumoniae, or Enterobacter species and also for empiric treatment of febrile neutropenic patients and urinary tract infections caused by Escherichia coli or Klebsiella pneumoniae for severe infections,
or, when concurrent bacteremia is present, for milder infections of Escherichia coli, Klebsiella pneumoniae, or Proteus mirabilis. It is also used to treat skin and skin structure infections caused by methicillin resistant strains of Staphylococcus aureus and Streptococcus pyogenes. It also used in combination with metronidazole for complicated intra abdominal infections caused by caused by many bacteria.
Mechanism of action
Like other cephalosporins and penicillins, cefepime works by binding to specific penicillin binding proteins and thus inhibiting the last stage of bacterial cell wall synthesis (the peptidoglycan layer), leading to autolysis of the bacterial cells by autolyic enzymes such as autolysins.
