    Abstract:
    We evaluated a newly developed quinolone agent, tosurofloxacin (TFLX), for its safety and clinical efficacy on patients with urinary tract infections (UTI). Among 138 cases satisfying the UTI criteria, 75 cases were acute simple UTI and 63 cases were chronic complicated UTI. In principle, a daily dose of 450 mg of TFLX was administered for 3 days and for 5 days for acute simple UTI and for chronic complicated UTI, respectively. Clinical efficacy of TFLX in these cases was evaluated according to the criteria of Japanese UTI committee. Bacteriologically, all 80 strains isolated from acute simple UTI were eradicated following TFLX administration. However, 2 gram positive strains and 1 gram negative strain, appeared following the treatment. In cases of chronic complicated UTI, 29 out of 32 gram positive strains and 29 out of 44 gram negative strains were eradicated. Among the isolated strains, P. aeruginosa and S. marcescens persisted, which suggests that they were less sensitive to TFLX. Overall clinical effectiveness rate of TFLX on acute simple UTI was 100%, while that on chronic complicated UTI was 73%. Adverse drug side effects were minimum, stomach discomfort and constipation was observed in one case each. These findings indicate that TFLX is a useful agent for the treatment of both simple and complicated UTI.
