Ceftaroline fosamil, when hydrolyzed to the active form ceftaroline, has a high affinity for penicillin binding protein 2a (PBP2a), which is associated with methicillin resistance. As a result, ceftaroline is unique in its activity against methicillin-resistant, vancomycin-intermediate, linezolid-resistant, and daptomycin-nonsusceptible strains."}]
