[Treatment of gonococcal urethritis with norfloxacin].
Fifty six males with gonococcal urethritis were administered 600 mg of norfloxacin (NFLX) daily for 7 days, before the effects were examined. The pharmaceutical effects were studied on the third and the seventh day after administration. Pronounced effectiveness of 77.8%, effectiveness of 19.4% and ineffectiveness of 2.8% were found on the third day after administration, and pronounced effectiveness of 94.4%, effectiveness of 5.6% and ineffectiveness of 0% were found on the seventh day after administration. Effectiveness of 100% was obtained up to the seventh day. Minimum inhibitory concentration (MIC) of NFLX and ampicillin (AMPC) were determined for 14 strains. The peak of MIC of NFLX was found at 0.05 micrograms/ml and all strains were 0.78 micrograms/ml or lower. The peak of MIC of AMPC was 0.1 microgram/ml. MICs of both drugs were 0.78 micrograms/ml or lower, and resistant bacteria were not found. In view of the analyses of age distribution of patients and source of infection, the peak was found in the twenties and the source of infection in 64.7% were, so-called, professional women.
