Answer

Cephalosporins, 3rd Generation

Third-generation cephalosporins are less active against gram-positive organisms than first-generation cephalosporins are. They are highly active against Enterobacteriaceae, Neisseria, and H influenzae.

Ceftriaxone (Rocephin)

Ceftriaxone is a third-generation cephalosporin with broad-spectrum gram-negative activity. It has lower efficacy against gram-positive organisms but excellent activity against susceptible pneumococcal organisms. It exerts an antimicrobial effect by interfering with the synthesis of peptidoglycan, a major structural component of the bacterial cell wall. It is an excellent antibiotic for the empiric treatment of bacterial meningitis.

Ceftazidime (Fortaz, Tazicef)

Ceftazidime is a third-generation cephalosporin with broad-spectrum activity against gram-negative organisms, lower efficacy against gram-positive organisms, and higher efficacy against resistant organisms. By binding to 1 or more of the penicillin-binding proteins, it arrests bacterial cell wall synthesis and inhibits bacterial replication.

Cefotaxime (Claforan)

Cefotaxime is a third-generation cephalosporin that is used to treat suspected or documented bacterial meningitis caused by susceptible organisms, such as H influenzae or N meningitidis. Like other beta-lactam antibiotics, cefotaxime inhibits bacterial growth by arresting bacterial cell wall synthesis.
