Product Description
Mechanism of action
Cefotaxime is a third‑generation cephalosporin known for strong gram‑negative activity and good CNS penetration. It binds multiple PBPs in Enterobacteriaceae and inhibits cell-wall synthesis. Its active metabolite, desacetyl‑cefotaxime, also possesses antimicrobial activity. It is a cornerstone molecule in meningitis research due to effective CSF penetration.
Benefits and advantages
Used in CNS infection modelling, PBPs binding studies, ESBL-producing organism research, neonatal sepsis models, β‑lactamase-resistance investigations and advanced cephalosporin SAR profiling.
Side effects and risks
Risks include hypersensitivity, GI symptoms, risk of C. difficile overgrowth, hepatic disturbances and rare neutropenia. Handle with antimicrobial precautions.
