Metabolite Identification
Common NamePefloxacin N-oxide
DescriptionPefloxacin N-oxide is a metabolite of pefloxacin. Pefloxacin is a synthetic chemotherapeutic agent used to treat severe and life threatening bacterial infections. Pefloxacin is commonly referred to as a fluoroquinolone drug and is a member of the fluoroquinolone class of antibacterials. It is an analog of norfloxacin. It is a synthetic fluoroquinolone, belonging to the 3rd generation of quinolones. Pefloxacin is extensively prescribed in France. Pefloxacin has not been approved for use in the United States.
