[Single-dose treatment of tosufloxacin (TFLX) for acute uncomplicated cystitis].

The effectiveness of a single 300-mg dose of tosufloxacin and of 3-day treatment with tosufloxacin (300 mg daily) were compared in a prospective trial in order to clarify the cost-effectiveness of tosufloxacin for acute uncomplicated cystitis. Fifty female patients (25 patients of each group) with acute uncomplicated cystitis received one of these treatment regimens, and the clinical data and follow-up culture results were analyzed. The effectiveness rates of single-dose treatment and 3-day treatment after 3 days were 100% and 96%, respectively. The recurrence rates of single-dose treatment and 3-day treatment after 14 or 28 days were 0% (0/13 patients) and 15% (2/13 patients), respectively. There was no significant difference in the effectiveness rate and the recurrence rate between these two groups, statistically. All isolated strains were eliminated in both regimens. From these results, it is suggested that single-dose treatment of tosufloxacin is effective enough for acute uncomplicated cystitis.
