Multicenter Study Clinical TrialClinical effects of 2 days of treatment by fosfomycin calcium for acute uncomplicated cystitis in women.
Fosfomycin calcium is a fosfomycin antimicrobial agent with a characteristic structure. After oral administration, the drug is absorbed and excreted via the kidneys in the unchanged form, without being metabolized in the body. It is, therefore, indicated for the treatment of urinary tract diseases, including cystitis and pyelonephritis. ⋯ When the patients were divided by age into an under 60 years of age group and an over 60 years of age group, the microbiological and clinical outcomes determined for evaluation of cure at visit 2 were 96.4 and 92.9%, respectively, and the corresponding rates determined for the evaluation of recurrence at visit 3 were 87.0 and 96.0%, respectively, in the under 60 years of age group. In the over 60 years of age group, the corresponding microbiological outcome and clinical outcome rates evaluated for cure were 90.9 and 100%, respectively, and those evaluated for recurrence were 50.0 and 60.0%, respectively. These results indicate the usefulness of fosfomycin calcium administered at 1 g three times daily for 2 days for acute uncomplicated cystitis.
