AIM: To compare the effects of ceftibuten and ofloxacin in treating urinary tract infections (UTI). METHODS: The 102 UTI patients (M 45, F 57; age 49 a± s 13 a) were divided randomly into two groups (each group including 51 patients). The ceftibuten group (31 secondry UTI patients and 20 primary UTI patients) were given ceftibuten 400 mg, po, qd for 10.4 d±2.7 d. The ofloxacin group (30 secondary UTI patients and 21 primary UTI patients) were given ofloxacin 100 mg, po, tid for 10 d±3 d. RESULTS: The total effect rate of two groups was 92 % and 76 %(P<0.05) respectively. The total bacterial clearance rate of two group was 92 % and 78 % (P>0.05) respectively. CONCLUSION: Ceftibuten is more effective than ofloxacin in treating UTI patients.
