title: Single dose piperacillin in treating uncomplicated gonococcal urethritis in men.
abstract: A single intramuscular dose of piperacillin 2 g, with probenecid 1 g orally, was used to treat 82 men with uncomplicated gonococcal urethritis due to penicillinase producing strains of Neisseria gonorrhoeae (PPNG) or non-PPNG. All 49 patients infected with non-PPNG strains were cured, as opposed to only 25 (76%) of 33 patients infected with PPNG strains, giving an overall success rate of 90%. No serious side effects of treatment were observed. Post gonococcal urethritis (PGU) occurred in 18% of the patients treated. Antibiotic susceptibility tests showed that 44 (96%) of the 46 non-PPNG strains tested had MICs of piperacillin of 2 mg/l or less and 26 (76%) of the 34 PPNG strains had MICs of 32 mg/l or more. This regimen is not recommended for use as first line treatment in areas where there is a high incidence of infection with PPNG strains. It is, however, highly effective against non-PPNG strains.
