Norfloxacin is a bactericidal antibiotic belonging to the quinolone class, used for the treatment of bacterial infectious diseases. A typical indication is urinary tract infections. Its effects are based on inhibition of bacterial DNA gyrase and topoisomerase IV. Norfloxacin should be taken at least one hour before or two hours after meals. It must not be combined with certain medications, as these may reduce its absorption into the body. The most common possible adverse effects include gastrointestinal disturbances, central nervous system disorders, skin rash, seizures, and vaginal candidiasis. Norfloxacin can cause photosensitivity and is an inhibitor of CYP1A2.
