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. Has an optimal pH of 4.5-6.5.

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.

Reconstitution

Following reconstitution, aliquot and freeze (-20°C) for long term storage or refrigerate (4°C) for short-term storage. Stock solutions are stable for up to 10 days at 4°C or for up to 13 weeks at -20°C.
