Oral sitafloxacin vs intravenous ceftriaxone followed by oral cefdinir for acute pyelonephritis and complicated urinary tract infection: a randomized controlled trial.

Background: The conventional antibiotic regimen for community-acquired upper urinary tract infections with moderate severity in Thailand is parenteral ceftriaxone (CTRX) for several days followed by oral cephalosporin for 7-14 days. The aim of this study was to compare the efficacy and safety of oral sitafloxacin (STFX) with that of intravenous CTRX followed by oral cefdinir (CFDN) for the therapy of acute pyelonephritis (APN) and complicated urinary tract infection (cUTI).

Methods: This open-label, randomized, controlled, noninferiority clinical trial included patients from nine centers across Thailand.
