Description
Cefotaxime binds 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. Cefotaxime blocks the division of cyanobacteria and lower plant organelles/plastids such as the photosynthetic organelles of Glaucophytes and chloroplasts of bryophytes. Cefotaxime is used to treat a variety of bacterial infections:
- Good coverage against most Gram-negative bacteria, with the notable exception of Pseudomonas
- Effective against most Gram-positive cocci, except for Enterococcus
- Active against penicillin-resistant strains of Streptococcus pneumoniae
- Modest activity against the anaerobic Bacteroides fragilis
- In meningitis, cefotaxime crosses the blood–brain barrier better than cefuroxime
