A comparative study of two different regimens of sparfloxacin versus doxycycline in the treatment of non-gonococcal urethritis in men.

Abstract

A multicentre, double-blind, randomised study comparing the efficacy and safety of oral sparfloxacin (200 mg on day 1 followed by 100 mg daily for 2 or 6 additional days) with doxycycline (200 mg once daily for 7 days) in the treatment of non-gonococcal urethritis in men was conducted. The overall success rates for the three treatment groups were statistically equivalent both at the end of treatment and at the follow-up visits. For chlamydial urethritis, the rates of relapse or possible reinfection were similar in the 7-day sparfloxacin and doxycycline groups. For ureaplasmal urethritis and urethritis of unknown aetiology, the rates of relapse or possible reinfection were lower in the 7-day sparfloxacin group than in the other two treatment groups. Sparfloxacin was well tolerated. A 7-day sparfloxacin regimen appears to be a useful alternative to doxycycline for the treatment of non-gonococcal urethritis in men.
