Ceftaroline (INN) (pronounced /sɛf tar ɒ liːn/) is a fifth-generation cephalosporin antibiotic. It is notable for its activity against Methicillin-resistant Staphylococcus aureus (MRSA) and Gram positive bacteria. It retains the activity of later generation cephalosporins having broad spectrum activity against Gram negative bacteria. It is currently being investigated for community-acquired pneumonia[1] and complicated skin and skin structure infection.[2][3][4]

Ceftaroline is being developed by Forest Laboratories, under a license from Takeda.[4] In vitro studies show that it has a similar spectrum to ceftobiprole, the only other fifth-generation cephalosporin to date, although no head to head clinical trials have been conducted. Currently, ceftaroline and ceftobiprole are on an unnamed subclass of cephalosporins by the Clinical and Laboratory Standards Institute (CLSI).


Mechanism of action

Beta-lactam antibiotics inhibit bacterial peptidoglycan synthesis by binding the penicillin binding proteins (PBPs) in the bacterial cell wall. Inhibition of PBPs leads to irregularities in cell wall structures, such as elongation, lesions, loss of selective permeability, and eventual cell death and lysis. In particular, ceftaroline can effectively bind to and inhibit PBP-2a, the type of PBP produced by MRSA and not well inhibited by other antibiotics currently in clinical use.[5][6]

Clinical use

Ceftaroline is a novel cephalosporin that has activity against MRSA with phase III clinical trials for complicated skin and skin structure infections with reported non-inferior efficacy against MRSA compared to vancomycin and aztreonam[2][3] Recently, ceftaroline has completed phase III clinical trials for community-acquired pneumonia comparing it against ceftriaxone with non-inferior results and similar adverse reaction profile.[1] However there are only published results for Phase II clinical trials in treatment of complicated skin and skin structure infections.[7] The manufacturer plans to file a New Drug Application (NDA) to the Food and Drug Administration by the end of this year for both community-acquired pneumonia and complicated skin and skin structure infections. [8]


Ceftaroline, also known as ceftaroline fosamil acetate, is a prodrug that is converted to active metabolite and inactive metabolite ceftaroline-M1. Initial in vitro and in vivo animal studies referred to Ceftaroline as TAK-599 and PPI-0903.[9][10]

Characteristic of cephalosporins, ceftaroline has a bicyclic ring with four member β-lactam ring fused to a six member cephem ring. Ceftaroline is thought to have activity against MRSA with its 1,3 thiazole ring.[11]
