Ceftolozane-tazobactam compared with levofloxacin in the treatment of complicated urinary-tract infections, including pyelonephritis: a randomised, double-blind, phase 3 trial (ASPECT-cUTI)

摘要

Background Treatment of complicated urinary-tract infections is challenging due to rising antimicrobial resistance. We assessed the efficacy and safety of ceftolozane-tazobactam, a novel antibacterial with Gram-negative activity, in the treatment of patients with complicated lower-urinary-tract infections or pyelonephritis.
