[Decreased incidence of postgonococcal urethritis following minocycline treatment compared to penicillin/spectinomycin].

Two groups of 30 patients each suffering from gonococcal urethritis were treated either with minocyclin for 7 days or with a single administration of penicillin or spectinomycin, respectively. 30% of them revealed an additional infection with C. trachomatis or U. urealyticum. On the 8th day, we observed remaining symptoms in only 20% of the patients treated with minocyclin, but in 40% of the group treated with penicillin/spectinomycin.
