Description

General description

Potent β-lactamase-resistant antibiotic of cephalosporin class. Active against Gram-positive and Gram-negative organisms, including Gram-negative anaerobes. Inhibits cell wall synthesis.

Biochem/physiol Actions

Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes.

Primary Target
Gram-positive

Secondary Target
Gram-negative

Packaging

Packaged under inert gas

Other Notes
