Cefpodoxime is an oral, third-generation cephalosporin antibiotic. It is active against most Gram-positive and Gram-negative organisms. Notable exceptions include Pseudomonas aeruginosa, Enterococcus, and Bacteroides fragilis. Currently, it is only marketed as generic preparations in the USA, according the FDA Orange Book. It is commonly used to treat acute otitis media, pharyngitis, sinusitis, and gonorrhea. It also finds use as oral continuation therapy when intravenous cephalosporins (such as ceftriaxone) are no longer necessary for continued treatment.

Spectrum of bacterial susceptibility and resistance
Cefpodoxime has been used to fight pathogenic bacteria responsible for causing gonorrhoea, tonsillitis, pneumonia, and bronchitis. Representative pathogenic genera include Streptococcus, Haemophilus, and Neisseria. The following represents MIC susceptibility data for a few medically significant microorganisms.
- Haemophilus influenzae: ≤0.03 - 1 μg/ml
- Neisseria gonorrhoeae: 0.004 - 0.06 μg/ml
- Streptococcus pyogenes: ≤0.004 - 2 μg/ml
