(HealthDay News) – Cefpodoxime should not be used as a first-line fluoroquinolone-sparing antimicrobial for acute uncomplicated cystitis, according to a study published in the Feb. 8 issue of the Journal of the American Medical Association.
Thomas M. Hooton, MD, of the University of Miami, and colleagues conducted a randomized, double-blind trial of 300 women (aged 18–55 years) with acute uncomplicated cystitis. Outcomes were assessed at 5–9 days and 28–30 days after completion of therapy. Patients were given 250mg of ciprofloxacin orally twice daily for three days or 100mg of cefpodoxime proxetil orally twice daily for three days. Clinical cure was defined as not requiring antimicrobial treatment during follow-up. Noninferiority was defined as <10% difference in the upper limit of the confidence interval for the primary outcome for ciprofloxacin minus cefpodoxime.
The researchers found that the overall clinical cure rate at the 30-day visit with the intent-to-treat approach in which patients lost to follow-up were considered as having clinical cure was 93% for ciprofloxacin compared with 82% for cefpodoxime. For the intent-to-treat approach in which patients lost to follow-up were considered as having not responded to treatment, the clinical cure rate was 83% for ciprofloxacin compared with 71% for cefpodoxime. The microbiological cure rate was 96% for ciprofloxacin compared with 81% for cefpodoxime. At first follow-up, 16% of women in the ciprofloxacin group had vaginal Escherichia coli colonization, compared with 40% of women in the cefpodoxime group.
“Among women with uncomplicated cystitis, a three-day regimen of cefpodoxime compared with ciprofloxacin did not meet criteria for noninferiority for achieving clinical cure,” the authors write.
