Drug Class: Cephalosporins, 3rd Generation
What is cefpodoxime, and what is it used for?
Cefpodoxime is a broad spectrum third-generation cephalosporin antibiotic used to treat a wide variety of bacterial infections. Cefpodoxime is effective against many strains of gram-negative and gram-positive bacteria including some strains that develop resistance to earlier generations of cephalosporins. Gram-negative and gram-positive bacteria are structurally different, and the types are identified by whether the bacteria get dyed or not in the Gram stain lab test.
Cefpodoxime kills bacteria (bactericidal) by inhibiting the synthesis of peptidoglycan, a vital constituent that provides stability to the bacterial cell wall. Cephalosporins are beta-lactam antibiotics that contain a beta-lactam ring in their chemical structure. Beta-lactam is a compound that targets and blocks penicillin-binding proteins, enzymes that are essential for the biosynthesis of peptidoglycan.
Some bacteria develop resistance to beta-lactam antibiotics by producing beta-lactamases, enzymes that cleave the beta-lactam rings in the antibiotics and destroy them. Cefpodoxime is effective for several bacterial strains despite the presence of beta-lactamases.
The brand Vantin has been discontinued in the USA, however, generic cefpodoxime is available.
Cefpodoxime is used to treat the following bacterial infections:
Adult
- Acute bronchitis and acute exacerbations of chronic bronchitis
- Acute community-acquired pneumonia
- Acute maxillary sinusitis
- Pharyngitis/tonsillitis
- Skin and skin structure infections
- Gonorrhea
- Urinary tract infections
Pediatric
- Acute maxillary sinusitis
- Acute otitis media (middle ear infection)
- Pharyngitis/tonsillitis
- Chronic bacterial bronchitis exacerbation
- Acute uncomplicated cystitis (bladder infection)
- Acute community-acquired pneumonia
Organisms susceptible to cefpodoxime include:
- Gram-positive bacteria: Staphylococcus aureus (methicillin-susceptible strains, including those producing penicillinases), Staphylococcus saprophyticus, Streptococcus pneumoniae (excluding penicillin-resistant isolates), Streptococcus pyogenes
- Gram-negative bacteria: Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Haemophilus influenzae (including beta-lactamase producing isolates), Moraxella catarrhalis, Neisseria gonorrhoeae (including penicillinase-producing isolates)
Warnings
- Do not take cefpodoxime if you are hypersensitive to cefpodoxime or cephalosporin group of antibiotics.
- Use cefpodoxime with caution in patients with a history of penicillin allergy or beta-lactam allergy.
- Bacterial and fungal overgrowth of non-susceptible organisms may occur with prolonged or repeated treatment with cefpodoxime.
- Use of nearly all antibacterial agents including cefpodoxime can cause Clostridium difficile overgrowth and associated diarrhea or colitis.
