ATC Group: J01DD Third-generation cephalosporins

Cefditoren is a cephalosporin with antibacterial activity against gram-positive and gram-negative pathogens. The bactericidal activity of cefditoren results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs).

Cefixime is an oral third generation cephalosporin which has marked in vitro bactericidal activity against a wide variety of Gram-positive and Gram-negative organisms.

Cefoperazone, a third-generation cephalosporin, interferes with cell wall synthesis by binding to the penicillin-binding proteins (PBPs), thus preventing cross-linking of nascent peptidoglycan. Cefoperazone is stable to penicillinases and has a high degree of stability to many beta-lactamases produced by gram-negative bacteria.

Cefotaxime exerts its action by binding to one or more of the penicillin-binding proteins (PBPs) which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thereby inhibiting cell wall synthesis.

Like other beta-lactam drugs, cefpodoxime exerts antibacterial activity by binding to and inhibiting the action of certain bacterial cell wall synthetic enzymes, namely the penicillin binding proteins.

Ceftazidime inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs). This results in the interruption of cell wall (peptidoglycan) biosynthesis, which leads to bacterial cell lysis and death.

Ceftibuten is a semisynthetic, beta-lactamase-stable, third-generation cephalosporin with antibacterial activity. Ceftibuten binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. This results in the weakening of the bacterial cell wall and causes cell lysis.

Ceftriaxone is an antibacterial for systemic use, a third-generation cephalosporin. It inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs) leading to bacterial cell lysis and death.
