Treatment of genital chlamydial infection with ofloxacin.

42 men and women with a genital chlamydial infection were randomly treated with a single dose of 200 mg doxycycline daily for ten days or with 200 mg ofloxacin twice a day for nine days. Two weeks after starting treatment 40 patients were able to be reassessed. All 12 men and all seven women treated with doxycycline had clinically improved or healed and had negative cultures for Chlamydia trachomatis. Among the patients treated with ofloxacin, all 11 males had improved or healed and C. trachomatis was not reisolated. These data are promising but larger numbers of patients and a longer follow-up are needed in order to confirm the efficacy of ofloxacin for the treatment of genital chlamydial infections.
