Ceftaroline fosamil is a prodrug of ceftaroline. It is active against methicillin-resistant Staphylococcus aureus (MRSA) and other Gram-positive bacteria. It retains some activity of later-generation cephalosporins having broad-spectrum activity against Gram-negative bacteria, but its effectiveness is relatively much weaker.
Ceftaroline has also been described as "fifth-generation" cephalosporin, but does not have the activity against Pseudomonas aeruginosa or vancomycin-resistant enterococci that ceftobiprole has. [36] Ceftolozane is an option for the treatment of complicated intra-abdominal infections and complicated urinary tract infections.

Ceftaroline has low water solubility but this problem was overcome by attaching a N-phosphonoamino group to the molecule making the intravenous prodrug ceftaroline fosamil. The prodrug is dephosphorylated in plasma to form active ceftaroline. [28] 5th generation cephalosporins: A) ceftaroline fosamil (prodrug); B) ceftobiprole medocaril (prodrug)
