Cefixime, an antibiotic, is a third-generation cephalosporin. Cefixime is highly stable in the presence of beta-lactamase enzymes. As a result, many organisms resistant to penicillin and some cephalosporin due to the presence of beta-lactamases may be susceptible to cefixime. The antibacterial effect of cefixime results from inhibition of mucopeptide synthesis in the bacterial cell wall.

Mechanism of Action
The bactericidal action of Cefixime is due to the inhibition of cell wall synthesis. It binds to one of the penicillin binding proteins (PBPs) which inhibit the final transpeptidation step of the peptidoglycan synthesis in the bacterial cell wall, thus inhibiting biosynthesis and arresting cell wall assembly resulting in bacterial cell death.
