title: Piperacillin v Carbenicillin in the therapy for serious infections.
abstract: One hundred seven patients were treated with either piperacillin (56) or carbenicillin (51) in an open randomized trial of hospitalized patients with pleuropulmonary (40), urinary tract (26), gynecologic (21), skin and soft-tissue (eight), joint (five), bone (three), and miscellaneous other infections (four). Patients with urinary tract infections were given 150 mg/kg/day of piperacillin sodium or 200 mg/kg/day or carbenicillin sodium in divided doses every six hours intravenously. Patients with other infections were given 250 mg/kg/day of piperacillin sodium and 450 mg/kg/day of carbenicillin sodium; 53/56 (95%) patients treated with piperacillin and 45/51 (88%) patients treated with carbenicillin were cured clinically. In general, the drugs were well tolerated. There were, however, more adverse experiences in the groups taking carbenicillin. Of special interest was the finding of liver function test abnormalities in 17/78 (21%) carbenicillin recipients (evaluative and nonevaluative cases). We concluded that piperacillin was effective and safe. It has potential for use in a great variety of infections.
