INTRODUCTION: The present study was performed to evaluate the efficacy and safety of a 10-day regimen of prulifloxacin 600 mg once daily as compared to ciprofloxacin 500 mg twice daily in the treatment of patients with complicated urinary tract infections (UTIs). MATERIALS AND METHODS: 257 patients (mean age +/- SD 62.3 +/- 16.5) were enrolled and orally treated with prulifloxacin (127 patients) or ciprofloxacin (130 patients). The study was designed as a randomized, double-blind, double-dummy, controlled clinical trial. The primary efficacy parameter was the eradication of infecting strains (<10(3) cfu/ml). The clinical outcome and tolerability were also assessed. RESULTS: At baseline, the most common infecting strains were Escherichia coli (62.8%), Proteus mirabilis (7.1%) and Klebsiella pneumoniae (4.1%). At the early follow-up, the rate of patients showing successful treatment was 90.8% in the prulifloxacin group, and 77.8% in the ciprofloxacin group (p = 0.008). A positive clinical outcome was observed in 94.8 and 93.3% of prulifloxacin- and ciprofloxacin-treated patients. Both drugs were well tolerated. Two patients dropped out for treatment-related adverse events. CONCLUSIONS: The high urinary concentrations of prulifloxacin, combined with a broad-spectrum antimicrobial activity, allow its use in the empiric therapy of UTIs.
