Second-generation cephalosporins maintain the gram-positive activity of first-generation cephalosporins, provide good coverage against Proteus mirabilis, H influenzae, E coli, K pneumoniae, and Moraxella species, and provide adequate activity against gram-positive organisms.

Of these agents, cefprozil, cefpodoxime, and cefuroxime seem to have better in vitro activity against S pneumoniae. Second-generation cephalosporins are not effective against Legionella or Mycoplasma species. These drugs are generally well tolerated, but cost may be a factor. Oral second-generation and third-generation cephalosporins offer increased activity against gram-negative agents and may be effective against ampicillin-resistant S pneumoniae.
