Cefpodoxime Generic Antibiotic Uses Warnings Side Effects Dosage

cefodoxime

Cefpodoxime is a third-generation cephalosporin antibiotic used to treat bacterial infections. It is effective against gram-negative and gram-positive bacteria and strains that are resistant to earlier generations of cephalosporins. Gram-negative and gram-positive bacteria are identified by the Gram stain lab test.

Cefpodoxime kills bacteria by inhibiting the synthesis of peptidoglycan, a vital component of the bacterial cell wall. It is a beta-lactam antibiotic that blocks penicillin-binding proteins, which are essential for peptidoglycan biosynthesis.

Some bacteria develop resistance to beta-lactam antibiotics by producing beta-lactamases, enzymes that destroy the antibiotics. However, cefpodoxime remains effective against many bacterial strains despite the presence of beta-lactamases.

The brand Vantin has been discontinued in the USA, but generic cefpodoxime is available.

Cefpodoxime is used to treat various bacterial infections:
