Description
Curator's Comment: description was created based on several sources, including: http://www.rxlist.com/maxipime-drug.htm https://www.drugs.com/cdi/cefepime.html

Cefepime is a fourth-generation cephalosporin antibiotic, which was developed in 1994. Cefepime has a broad spectrum in vitro activity that encompasses a wide range of Gram-positive and Gram-negative bacteria. Within bacterial cells, the molecular targets of cefepime are the penicillin binding proteins (PBP). It is FDA approved for the treatment of pneumonia, febrile neutropenia, uncomplicated UTI, uncomplicated skin infection and complicated intraabdominal infections. Common adverse reactions include rash, hypophosphatemia, diarrhea. Cefepime is metabolized to N-methylpyrrolidine (NMP) which is rapidly converted to the N-oxide (NMP-N-oxide). Urinary recovery of unchanged cefepime accounts for approximately 85% of the administered dose. Less than 1% of the administered dose is recovered from urine as NMP, 6.8% as NMP-N-oxide, and 2.5% as an epimer of cefepime. Because renal excretion is a significant pathway of elimination, patients with renal dysfunction and patients undergoing hemodialysis require dosage adjustment.

CNS Activity

Curator's Comment: It has been confirmed that the concentration of cefepime in cerebrospinal fluid (CSF) could reach the 10% of its concentration in plasma, exceeding the inhibitory concentration to 90% of organisms (MIC(90)) for common bacteria. However, the blood-brain barrier (BBB) penetration ability of cefepime is still unclear

Approved Use

Cefepime for injection, USP is indicated in the treatment of the following infections caused by susceptible strains of the designated microorganisms (see also PRECAUTIONS: Pediatric Use and DOSAGE AND ADMINISTRATION ): Pneumonia (moderate to severe) caused by Streptococcus pneumoniae, including cases associated with concurrent bacteremia, Pseudomonas aeruginosa, Klebsiella pneumoniae , or Enterobacter species. Empiric Therapy for Febrile Neutropenic Patients. Cefepime as monotherapy is indicated for empiric treatment of febrile neutropenic patients. In patients at high risk for severe infection (including patients with a history of recent bone marrow transplantation, with hypotension at presentation, with an underlying hematologic malignancy, or with severe or prolonged neutropenia), antimicrobial monotherapy may not be appropriate. Insufficient data exist to support the efficacy of cefepime monotherapy in such patients. (See CLINICAL STUDIES .) Uncomplicated and Complicated Urinary Tract Infections (including pyelonephritis) caused by Escherichia coli or Klebsiella pneumoniae, when the infection is severe, or caused by Escherichia coli, Klebsiella pneumoniae , or Proteus mirabilis, when the infection is mild to moderate, including cases associated with concurrent bacteremia with these microorganisms. Uncomplicated Skin and Skin Structure Infections caused by Staphylococcus aureus (methicillin-susceptible isolates only) or Streptococcus pyogenes. Complicated Intra-abdominal Infections (used in combination with metronidazole) caused by Escherichia coli, viridans group streptococci, Pseudomonas aeruginosa, Klebsiella pneumoniae , Enterobacter species, or Bacteroides fragilis. (See CLINICAL STUDIES .) To reduce the development of drug-resistant bacteria and maintain the effectiveness of cefepime for injection, USP and other antibacterial drugs, cefepime for injection, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
