Summary: | This report presents the pooled results from two randomized trials of lomefloxacin and cefotaxime used as prophylaxis in patients undergoing transurethral surgical procedures. A total of 499 patients were enrolled at seven centers in the United States. Patients received either 400 mg of lomefloxacin orally 2–6 hours prior to surgery, or 1 g of cefotaxime intravenously or intramuscularly 30–90 minutes preoperatively. Patients undergoing simple cystoscopy or retrograde pyelograms were not eligible for inclusion. Urine cultures were obtained prior to surgery, 24 hours post-surgery, prior to catheter removal, and 3–5 days post operatively. Treatment failure was defined as isolation of ≥10
5 colony-forming units (CFU)/mL of pathogenic bacteria from any post-surgical urine culture. Lomefloxacin was successful in preventing post operative infections in 204 of 207 evaluable patients (98.6%); there were three prophylactic failures. Cefotaxime was successful in 196 of 206 (95.1%) evaluable patients; 10 were prophylactic failures. Lomefloxacin concentrations were measured simultaneously in serum and in samples of prostate tissue from 29 patients undergoing transurethral resection of the prostate. Lomefloxacin prostate concentrations were 1.0–22.3 μg/g, with a mean of 5.0 μg/g. The average tissue:plasma ratio was 2.0. The safety profile of the two study drugs was excellent, and both were well tolerated. Adverse events were reported by 12.7% of the patients treated with lomefloxacin and 13.8% of those treated with cefotaxime. The majority of events were mild and required no treatment. |
