Sixty-seven patients with complicated urinary tract infections were randomized in double-blind fashion to ceftazidime or moxalactam (MOX). A total of 54 patients were evaluable, 27 in each group. Patients received 500 mg of antibiotic intravenously every 12 h, except for those with Pseudomonas aeruginosa randomized to MOX who received 2 g intravenously every 12 h. Toxic effects with ceftazidime were experienced by the following number of patients: pain with infusion, one; posttherapy diarrhea, one; liver function test elevations, two; and neutropenia, one. Toxic effects with MOX were experienced by the following number of patients: liver function test elevations, two; and prolonged prothrombin time, one. All resolved. At 1 week posttherapy, bacteriologic results were 74% cured, 11% relapsed, 15% reinfection with ceftazidime and 52% cured, 33% relapsed, and 19% reinfection with MOX. Ceftazidime was effective for infections caused by MOX-resistant P. aeruginosa. P. aeruginosa resistant to MOX and other beta-lactams was isolated from one patient after MOX therapy. Enterococcal reinfarction was common in both groups.
