Norfloxacin is a synthetic chemotherapeutic antibacterial agent. Norfloxacin is a first generation synthetic fluoroquinolone (quinolone).Norfloxacin interacts with a number of other drugs, as well as a number of herbal and natural supplements. Norfloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It functions by inhibiting DNA gyrase, a type II topoisomerase, and topoisomerase IV, enzymes necessary to separate bacterial DNA, thereby inhibiting cell division. Norfloxacin has been reported to rapidly cross the blood-placenta and blood-milk barrier, and is extensively distributed into the fetal tissues.
