Amoxycillin/clavulanic acid ('Augmentin') compared with a combination of aminopenicillin, aminoglycoside and metronidazole in the treatment of pelvic inflammatory disease.

A randomized, multi-centre trial was carried out in 152 hospitalized women with pelvic inflammatory disease to evaluate the efficacy and tolerability of amoxycillin/clavulanic acid compared with that of a standard regimen using three antimicrobial agents (aminopenicillin, an aminoglycoside and metronidazole). Seventy patients initially received 3 to 4 intravenous doses per day of 1 g amoxycillin/200 mg clavulanic acid (mean 7.7 days) and then 4 to 6 tablets per day of 500 mg amoxycillin/125 mg clavulanic acid (mean 11.2 days). The other group of 82 patients initially received parenteral therapy daily (mean 7.7 days) with a combination of 3 to 4 g amoxycillin or ampicillin, 160 mg gentamicin (or 150 mg dibekacin or tobramycin) and 1.5 g metronidazole, and then oral therapy with 2 to 3 g amoxycillin or ampicillin and 1 to 1.5 g metronidazole daily (11.1 days). Clinical results, assessed at discharge from hospital (mean 10 days in both groups), were comparable in both groups, with 96% complete or partial response and no failures in the amoxycillin/clavulanic acid group, and 90% complete or partial successes and 5 failures with the triple therapy regimen. Both treatments were well tolerated and very few side-effects were reported.
