• Description: Fleroxacin is a new, once daily trifluoroquinolone antibacterial structurally related to norfloxacin. Available in both oral and IV formulations, it is reportedly useful in the treatment of gonorrhea, bacterial enteritis, chronic bronchitis and urinary tract infections. Fleroxacin has a longer serum half-life (9-12 hours) than other drugs of this class, such as ciprofloxacin, enoxacin and norfloxacin.
• Uses: antibiotic
• Therapeutic Function: Antibacterial
