Indication |
For the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms. |
Pharmacodynamics |
Cefpodoxime is an oral third generation cephalosporin
antibiotic. It is active against most Gram positive and Gram negative
bacteria. Notable exceptions include Pseudomonas aeruginosa, Enterococcus, and Bacteroides fragilis. |
Mechanism of action |
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. |
Absorption |
Cefpodoxime proxetil is a prodrug that is absorbed from the
gastrointestinal tract and de-esterified to its active metabolite,
cefpodoxime. Following oral administration of 100 mg of cefpodoxime
proxetil to fasting subjects, approximately 50% of the administered
cefpodoxime dose was absorbed systemically. |

29 to 33% of the administered cefpodoxime dose was excreted unchanged in
the urine in 12 hours. |
