Treatment of uncomplicated gonococcal infection with trimethoprim-sulfamethoxazole.
The efficacy of trimethoprim-sulfamethoxazole (TMP-SMZ; 80 mg of TMP and 400 mg of SMZ per tablet; nine tablets taken once daily for three days; total, 27 tablets) was compared with the U.S. Public Health Service recommended regimen of 2 g of tetracycline daily for five days for the treatment of uncomplicated genital gonorrhea. Fourteen (3%) of the 461 patients treated with tetracycline and 24 (5%) of the 477 patients treated with TMP-SMZ failed to be cured; the difference between the two groups was not significant. Treatment of patients with TMP-SMZ was more likely to fail if the isolates of Neisseria gonorrhoeae had MICs of > or = 0.5 microgram of TMP/ml and > or = 9.5 micrograms of SMZ/ml. Adverse effects were more often reported by patients receiving TMP-SMZ. The results show that TMP-SMZ is an effective therapy for uncomplicated gonococcal infections in men and women and may also eliminate agents causing postgonococcal urethritis. The utility of this drug combination may be limited by the adverse effects that are associated with the large dose used.[1]References
