Gatifloxacin 400 mg as a single shot or 200 mg once daily for 3 days is as effective as ciprofloxacin 250 mg twice daily for the treatment of patients with uncomplicated urinary tract infections.
The efficacy and safety of two oral dosing regimens of gatifloxacin compared with ciprofloxacin for the treatment of acute uncomplicated lower urinary tract infection was investigated in a double-blind, randomised study, in adult female patients who received either gatifloxacin (400 mg as a single shot or 3 days of 200 mg once daily) or ciprofloxacin (250 mg given twice daily for 3 days). Bacteriological and clinical responses were assessed 7-9 days after the end of treatment (EOT), and 4-6 weeks post-treatment (end of study, EOS). One thousand one hundred and two women were treated, 741 (248 in the gatifloxacin 400 mg group, 252 in the gatifloxacin 200 mg group, and 241 in the ciprofloxacin group) presented with bacteriological proof of infection and entered the efficacy analysis. The bacteriological response per patient at EOT in the three groups were 80% (177/220) [95% CI to ciprofloxacin -8.4%; 6.4%], 83% (184/222) [95% CI to ciprofloxacin -5.9%; 8.7%] and 81% (176/216), respectively. At the follow-up assessment they were slightly lower, 75% (167/224), 79% (169/213) and 79% (171/217), respectively. The clinical responses at EOT were 81% (197/243) [95% CI to ciprofloxacin -10.2%; 3.4%], 85% (213/250) [95% CI to ciprofloxacin -5.7%; 7.2%] and 85% (201/238), respectively. At EOS they were 82% (195/239), 88% (212/241) and 86% (200/233), respectively. The eradication rates for all initial pathogens at the EOT were 90.3% in the gatifloxacin 400 mg S.D. group, 90.6% in the gatifloxacin 200 mg group, and 88.3% in the ciprofloxacin group. All treatment groups showed a similar safety profile. The incidence of treatment-related adverse events was comparable, the majority of adverse events were of mild or moderate intensity and the medications were well tolerated. Both the administration of gatifloxacin 200 mg once daily for 3 days, and gatifloxacin 400 mg as a single shot were shown to be equivalent to ciprofloxacin 250 mg twice daily for 3 days for the treatment of acute uncomplicated lower urinary tract infections.
