Results from the simulations indicated that the penetration of ceftaroline into the cerebrospinal fluid was dependent on the degree of meningeal inflammation, suggesting that inflammation associated with infection would provide adequate antibiotic exposure, similar to other β-lactam antibiotics. Ceftaroline has a potential, unique role as a β-lactam antibiotic in the treatment of MRSA and coagulase negative staphylococci causing CNS infections as an alternative to vancomycin, the current standard of care. Support for treatment of CNS infections may be derived from further cerebrospinal fluid PK studies followed by PK/PD modeling prior to the conduct of prospective phase 2/3 clinical studies aimed at assessing the efficacy and safety of ceftaroline for the treatment of pediatric CNS infections.

The literature review identified 150 relevant articles, deriving 19 recommendations based on the GRADE framework.
