Summary of evidence and Expert Committee recommendations
The Expert Committee recommended the inclusion of ceftolozane + tazobactam as Reserve group antibiotic on the complementary list of the EML and EMLc for the treatment of infections caused or suspected to be caused by carbapenem-resistant Pseudomonas aeruginosa, a “Critical” priority pathogen on the 2017 WHO Priority Pathogens List. The Committee acknowledged that the clinical evidence for efficacy of ceftolozane + tazobactam against this specific pathogen is limited but considered that the availability of carbapenem-sparing alternatives for treatment of drug-resistant Pseudomonas aeruginosa was important as part of the strategy to limit/prevent further emergence and spread of carbapenem-resistant organisms.
