Mechanism action of Cefpodoxime
Cefpodoxime is active against a wide spectrum of Gram-positive and
Gram-negative bacteria. Cefpodoxime is stable in the presence of
beta-lactamase enzymes. As a result, many organisms resistant to
penicillins and cephalosporins, due to their production of
beta-lactamase, may be susceptible to cefpodoxime. Cefpodoxime is
inactivated by certain extended spectrum beta-lactamases. The
bactericidal activity of cefpodoxime results from its inhibition of cell
wall synthesis. The active metabolite of cefpodoxime binds
preferentially to penicillin binding protein 3, which inhibits
production of peptidoglycan, the primary constituent of bacterial cell
walls.
