Safety and efficacy of lomefloxacin versus norfloxacin in the treatment of complicated urinary tract infections

Seventy patients with complicated urinary tract infections were treated with either lomefloxacin (400 mg once daily) or norfloxacin (400 mg twice daily) for 10 to 14 days. A total of 19 (86%) of 22 patients treated with lomefloxacin and 20 (74%) of 27 patients treated with norfloxacin were cured, as defined by a negative culture five to nine days after completion of therapy (p = 0.09). After four to six weeks, the figures were 56% for lomefloxacin and 48% for norfloxacin. Adverse effects in the lomefloxacin group were observed on 20 occasions in 12 patients (one stopped treatment) compared to nine occasions in five patients treated with norfloxacin (difference not significant).
