NCIt definition : A third generation semi-synthetic cephalosporin and a beta-lactam antibiotic with
bactericidal activity. Cefpodoxime's effect is dependent on its binding to penicillin-binding
proteins (PBPs) located in the bacterial cytoplasmic membrane. Binding results in
the inhibition of the transpeptidase enzymes, thereby preventing cross-linking of
the pentaglycine bridge with the fourth residue of the pentapeptide and interrupting
consequent synthesis of peptidoglycan chains. As a result, cefpodoxime inhibits bacterial
septum and cell wall synthesis formation.;
