  • Ceftolozane/tazobactam (Zerbaxa) is indicated for the treatment of Complicated Intra-abdominal Infections in adults when used with metronidazole, and for treating Complicated Urinary Tract Infections including Pyelonephritis in adults and pediatric patients. It is also used for adults with Hospital-acquired Bacterial Pneumonia and Ventilator-associated Bacterial Pneumonia.
  • Twenty studies provided insights into the safety, effectiveness, and considerations for specific populations or subgroups related to ceftolozane/tazobactam compared to other antimicrobial agents.
  • The drug showed comparable performance against infections caused by Pseudomonas aeruginosa and complicated intra-abdominal infections when compared with novel β-lactams such as ceftazidime-avibactam and cefiderocol. Its efficacy was similar to carbapenems, making it a potential alternative option.
  • For cases of nosocomial pneumonia, ceftolozane-tazobactam emerged as a preferred antibiotic based on network meta-analysis results. Additionally, its use among newborns and pediatric populations demonstrated favorable outcomes, especially against multi-drug-resistant gram-negative infections.
  • Compared with treatments involving polymyxins and aminoglycosides, Zerbaxa had a significantly lower risk of causing acute kidney injury, indicating a better nephrotoxicity safety profile. Observational data suggested its utility in contexts of bloodstream infections due to generally favorable responses.
  • High clinical success rates were observed while using the drug for treating Multi-drug Resistant Organisms, specifically MDR & XDR strains of Pseudomonas aeruginosa, highlighting its value against highly resistant pathogens.
  • Comparative studies highlighted the nuanced positioning of Zerbaxa depending on the type of infection, resistance patterns, and healthcare settings; cost-effectiveness analyses also underscored its potential.
  • Subpopulation considerations revealed promising outcomes with ceftolozane/tazobactam for neonates and children suffering from MDR Gram-negative infections. Patients with complicated UTIs experienced better clinical outcomes and lower resistance rates compared to treatments with piperacillin/tazobactam, emphasizing Zerbaxa's role in urinary tract infections.
