Efficacy and safety of gatifloxacin for urinary tract infection in nonspecialized Korean urologic practice.

To investigate the efficacy and safety of gatifloxacin (400mg/day) on chronic prostatitis or cystitis, 453 patients with prostatitis (NIH category II or IIIa) (N=149, mean 45.8+/-13.3 years) and cystitis (N=304, mean 53.8+/-14.3 years) were enrolled. Total NIH CPSI score and symptom score for cystitis decreased from 20.3 to 9.9 (response rate 86.7%, 95% CI 80.2-93.2%) and from 6.2 to 1.8 (response rate 83.2%, 95% CI 78.7-87.7%), respectively. In the overall clinical efficacy, 71.2% and 88.4% of the patients with prostatitis and cystitis were responders, respectively. Of the patients, 15.7% reported insignificant adverse events. These results suggest that gatifloxacin was well tolerated and improved the clinical outcomes in patients with chronic prostatitis or cystitis.
