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.

Mode of Action: Inhibits bacterial cell wall synthesis.

Primary Target
Gram-positive

Secondary Target
Gram-negative

Packaging

Packaged under inert gas

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 3 months at -20°C.

Other Notes

Broad spectrum third generation cephalosporin antibiotic.
