Aurobindo Pharma acquires Cefepime

Bangalore, Aug 27, 2009: Hydebadad-India based Aurobindo Pharma has received Swiss drug regulator Swissmedic's approval for the license of Cefepime APL for Injection 1g and 2g.

A press release by Aurobindo said Cefepime APL for Injection 1g and 2g falls under the anti-beta-lactam segment and is indicated for Moderate to severe pneumonia, septicaemia, UTI, skin & skin structure infections, intra-abdominal infections.This is Aurobindo’s second product approval in Switzerland.

But without going much into it in this article I wish to focus on some basic information on Cefepime.

Cefepime (pronounced /ˈsɛfəpiːm/, /ˈkɛfəpiːm/) is a fourth-generation cephalosporin antibiotic developed in 1994. Cefepime has an extended spectrum of activity against Gram-positive and Gram-negative bacteria, with greater activity against both Gram-negative and Gram-positive organisms than third-generation agents. Cefepime hydrochloride was first marketed in 1994 and is currently marketed under various trade names including Maxipime, Maxcef, Cepimax, Cepimex, and Axepim. A 2007 meta-analysis suggested that when data of trials were combined, mortality was increased in patients 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 that there was no mortality difference.

Cefepime is usually reserved to treat severe nosocomial pneumonia, infections caused by multi-resistant microorganisms (e.g. Pseudomonas aeruginosa) and empirical treatment of febrile neutropenia. The use of cefepime might become less common, since it has been associated to an increase mortality when used for different types of infections.

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.

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 increases the activity of cefepime against otherwise resistant organisms including Pseudomonas aeruginosa and Staphylococcus aureus.
