title: Randomized controlled clinical trial on the efficacy of fosfomycin trometamol for uncomplicated gonococcal urethritis in men.
abstract: We assessed the efficacy of fosfomycin trometamol in treating uncomplicated gonococcal urethritis in men. We conducted an open randomized controlled trial in 152 consecutive men with any main complaints suggestive of uncomplicated gonococcal urethritis in Dujiangyan Medical Center between 1 September 2013 and 31 August 2015. In total, 126 patients completed all aspects of this study. Sixty were provided therapy with fosfomycin trometamol 3 g orally on days 1, 3 and 5 in the intervention group; the other 61 were provided ceftriaxone 250 mg intramuscularly plus azithromycin 1 g orally simultaneously as a single dose in the control group. The primary outcomes involved clinical and microbiologic cure on days 7 and 14 after receipt of all the study medications. At the day 7 follow-up visit, all the 121 participants had complete resolution of clinical symptoms and signs. In addition, five patients (two in the intervention group and three in the control group) discontinued intervention because of unsuccessful treatment. After receipt of all the study medications, these five patients still had urethral purulent discharge and were switched to other unknown treatment regimens by other doctors. The bacterial smears and cultures of urethral or urine specimens in the 121 patients who completed all aspects of the study were negative on a test-of-cure visit. In the per-protocol analysis, both clinical and microbiologic cure were experienced by 96.8% (60/62 patients) in the intervention group and 95.3% (61/64 patients) in the control group. There were no recurrences at the day 14 test-of-cure visit. This trial indicates that fosfomycin trometamol exhibits excellent efficacy for treatment of uncomplicated gonococcal urethritis in men. Serious adverse effects are rare.
