    A single supervised oral dose of amoxycillin 3 g combined with clavulanic acid 125 mg as a suspension (Augmentin 3.125G) plus probenecid 1 g, cured 97 of 100 assessable patients who had uncomplicated anogenital gonorrhoea. Thirteen of the 100 patients were infected with penicillinase producing strains of Neisseria gonorrhoeae (PPNG) and 11 (85%) of these patients were cured, including one infected with a PPNG strain that was also resistant to spectinomycin. Another group of 93 assessable patients was treated with ampicillin 3 g plus probenecid 1 g, and only 85 (91%) patients were cured. Of the eight treatment failures in this group, five were found to be infected with PPNG strains. In a second study 144 assessable patients were treated with amoxycillin 3 g combined with clavulanic acid 250 mg, (Augmentin 3.250G) plus probenecid 1 g, and a 97% cure rate was again obtained. Five of seven (71%) patients infected with PPNG strains were cured. Although both Augmentin regimens were effective for treating gonorrhoea caused by PPNG and non-PPNG strains, side effects were noted in more patients treated with 250 mg clavulanic acid (24%) than with 125 mg clavulanic acid (5%). In addition, a similar cure rate was obtained in the three primary sites of infection, the urethra, cervix, and rectum.
