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 59 days and 46 weeks after completion of treatment.
Results: There was no significant difference among the three treatment groups: overall efficacy ranged from 78.5% for the trimethoprim/sulfamethoxazole group, to 84.5% for the ciprofloxacin group. The highest overall incidence of drug-related adverse effects occurred in the trimethoprim/sulfamethoxazole patients.
Conclusions: These data indicate that a 3 day treatment with ciprofloxacin is at least as clinically and bacteriologically effective as 7 day treatments with trimethoprim/sulfamethoxazole and norfloxacin for uncomplicated lower urinary tract infections.
