Effect of penicillin and spectinomycin given for urethritis and cervicitis with Neisseria gonorrhoeae: high prevalence of penicillin-resistant isolates.

Efficacy of single-dose spectinomycin (TRO: 2 g intramuscularly) was compared with that of aqueous procaine penicillin G (APPG:4.8 x 10(6) units) plus 1 g of probenecid for treatment of gonococcal urethritis and cervicitis. Cure rates of the 210 patients who received TRO and 190 patients who received APPG were 97.
