Comparison of short-term treatment regimen of ciprofloxacin versus long-term treatment regimens of trimethoprim/sulfamethoxazole or norfloxacin for uncomplicated lower urinary tract infections: a randomized, multicentre, open-label, prospective study.

Objective: To compare the bacteriological and clinical efficacy of three treatments for uncomplicated cystitis in ambulatory pre-menopausal women: ciprofloxacin 250 mg orally twice daily for 3 days, trimethoprim/sulfamethoxazole 160/800 mg orally twice daily for 7 days, and norfloxacin 400 mg orally twice daily for 7 days.

Materials And Methods: A total of 455 women were randomly assigned to three treatment groups: 151 received ciprofloxacin, 150 received trimethoprim/sulfamethoxazole, and 154 received norfloxacin. Bacteriological cure and clinical resolution were evaluated 5-9 days and 4-6 weeks after completion of treatment.
