Ceftaroline

Q: Ceftaroline has been called fifth generation cephalosporin because it has added activity against?

A) Methicillin-resistant Staphylococcus aureus (MRSA)
B) Pseudomonas aeruginosa
C) Neisseria gonorrhoeae
D) Klebsiella
E) Moraxella catarrhalis


Answer: A

Ceftaroline and ceftobiprole are the only two fifth generation cephalosporins known.

This took care of criticism on cephalosporins of being "LAME" - as they had  no activity  against Listeria, Atypicals (including Mycoplasma and Chlamydia), MRSA, and enterococci.
