  • Title: Fleroxacin versus norfloxacin for oral treatment of serious urinary tract infections.
    Author: Childs SJ.
    Journal: Am J Med; 1993 Mar 22; 94(3A):105S-107S. PubMed ID: 8452164.
    Abstract:
    Fleroxacin, 400 mg once daily, and norfloxacin, 400 mg twice daily, both administered orally, were compared for the treatment of serious urinary tract infections (UTIs). In total, 301 patients from multiple centers who had serious UTIs were randomized to receive fleroxacin or norfloxacin in a double-blind study. The demographic parameters of the two groups were similar. A total of 190 patients were evaluable for efficacy, 94 in the fleroxacin group and 96 in the norfloxacin group. The reasons for exclusion from the efficacy analysis were not significantly different in the two groups, but more patients receiving fleroxacin were prematurely withdrawn from the study. The majority (134) of the diagnoses were complicated UTI, and the pathogens were primarily Enterobacteriaceae. The clinical responses were cure or improvement in 98% of the fleroxacin group and 92% of the norfloxacin group and failure in 2% of the fleroxacin group and 7% of the norfloxacin group. The bacteriologic results by infection were cure in 98% of the fleroxacin group and 89% of the norfloxacin group (including cure with superinfection in 4% of the fleroxacin group and 5% of the norfloxacin group) and failure in 2% of the fleroxacin group and 11% of the norfloxacin group. Adverse events were more common in the fleroxacin group and were mostly nausea, insomnia, and headache. Fleroxacin, 400 mg once daily, was as effective as norfloxacin, 400 mg twice daily, in eradicating UTIs but was associated with more adverse events.
