Description

General description

Norfloxacin is an antimicrobial drug, belonging to the class of fluoroquinolones (FQs), which shows broad-spectrum activity against a wide range of Gram-negative and Gram-positive organisms.

Application

Norfloxacin may be used as an analytical reference standard for the determination of the analyte in pharmaceutical formulations, biological fluids and sewage using various chromatography techniques.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Biochem/physiol Actions

Norfloxacin blocks DNA replication by interfering with an ATP-induced structural transition of DNA complexed with DNA gyrase (topoisomerase).
Mode of action: inhibits bacterial DNA replication
