Applicazioni

A broad spectrum antibiotic. Cefpodoxime proxetil is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against gram positive and gram negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options for infected patients. Product is to be used for research and development only.

Note

Research Use only: Not intended for animal or human diagnostic or therapeutic use.

Like β-lactams, cephalosporins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to cephalosporins is commonly due to cells containing plasmid encoded β-lactamases. However, like many cephalosporins, cefpodoxime is stable in the presence of β-lactamases.

Cefpodoxime proxetil is a broad spectrum antibiotic which targets a wide variety of gram positive and gram negative bacteria especially those which cause otitis media and pharyngitis.
