Norfloxacin is a broad- norfloxacin; spectrum antimicrobial fluoroquinolone used against Gram-positive and Gram-negative organisms pharmacokinetics; quality control (aerobic organisms). There are different analytical methods available to determine norfloxacin applied in quality control of this medicine in order to ensure its effectiveness and safety. The authors present an overview of the fourth generation of quinolones, followed by the properties, applications, and analytical methods of norfloxacin. These results show several existing analytical techniques that are flexible and broad-based methods of analysis in different matrices. This article focuses on bionalytical and pharmaceutical quality-control applications, such as thin-layer chromatography, microbiological assay, spectrophotometry, capillary electrophoresis (CE), and high-performance liquid chromatography (HPLC). Introduction important goals of quality control is to report the analytical method validation to ensure confidence in the analytical data Quinolones and fluoroquinolones are chemical groups related throughout product development (International Conference on to nalidixic acid derivatives.
