Cefepime induced jaw myoclonus
Cefepime is a fourth-generation cephalosporin antibiotic. Cefepime has an extended spectrum of activity against Gram-positive and Gram-negative bacteria, with greater activity against both types of organism than third-generation agents.

A 2007 meta-analysis suggested when data of trials were combined, mortality was increased in people treated with cefepime compared with other β-lactam antibiotics. In response, the U.S. Food and Drug Administration performed their own meta-analysis which found no mortality difference.
Cefepime was developed by Bristol-Myers Squibb and marketed beginning in 1994. It is now available as a generic drug and sold under a variety of trade names worldwide.
Medical use
Cefepime is usually reserved to treat moderate to severe nosocomial pneumonia, infections caused by multiple drug-resistant microorganisms (e.g. Pseudomonas aeruginosa) and empirical treatment of febrile neutropenia.
Cefepime has good activity against important pathogens including Pseudomonas aeruginosa, Staphylococcus aureus, and multiple drug-resistant Streptococcus pneumoniae. A particular strength is its activity against Enterobacteriaceae. Whereas other cephalosporins are degraded by many plasmid- and chromosome-mediated beta-lactamases, cefepime is stable and is a front-line agent when infection with Enterobacteriaceae is known or suspected.
Spectrum of bacterial susceptibility
Cefepime is a broad-spectrum cephalosporin antibiotic and has been used to treat bacteria responsible for causing pneumonia and infections of the skin and urinary tract. Some of these bacteria include Pseudomonas, Escherichia, and Streptococcus species. The following represents MIC susceptibility data for a few medically significant microorganisms.
Chemistry
The combination of the syn-configuration of the methoxyimino moiety and the aminothiazolyl moiety confers extra stability to β-lactamase enzymes produced by many bacteria. The N-methylpyrrolidine moiety increases penetration into Gram-negative bacteria. These factors increase the activity of cefepime against otherwise resistant organisms including Pseudomonas aeruginosa and Staphylococcus aureus.
Trade names
Following expiration of the Bristol-Myers Squibb patent, cefepime became available as a generic and is now marketed by numerous companies worldwide under tradenames including Neopime (Neomed), Maxipime, Cepimax, Cepimex, and Axepim.
