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 to 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.
