    Cefpodoxime Sodium

    10,443,300.00₫

    Cefpodoxime Sodium is a broad-spectrum, semi-synthetic, third-generation cephalosporin β-lactam and bactericidal agent that interferes with the bacterial cell wall.  It is effective against a wide range of Gram-positive and Gram-negative bacteria. In vivo, it is de-esterified to the free acid and active metabolite, Cefpodoxime.  Cefpodoxime, patented in 1980, is stable in the presence of β-lactamase enzymes, so many organisms resistant to penicillins and cephalosporins due to their production of β-lactamase, may be susceptible to Cefpodoxime.  The compound is inactivated by certain extended-spectrum β-lactamases. 

    Cefpodoxime Sodium is soluble in DMSO.

    We also offer:

    •  Cefpodoxime Proxetil (C015)
    •  Cefpodoxime Free Acid (C016)
    Mechanism of Action 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.
    Spectrum Cefpodoxime Sodium is a broad-spectrum antibiotic which targets a wide variety of Gram-positive and Gram-negative bacteria.  Notable exceptions include Pseudomonas aeruginosa, Enterococcus, and Bacterioides fragilis.
    Microbiology Applications Cefpodoxime Sodium 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. Representative MIC values include:
    • Klebsiella pneumoniae 8 µg/mL - 64 µg/mL
    • Haemophilus influenzae 0.032 µg/mL – 1 µg/mL

    In vitro kinetic modeling can be used to study the pharmacokinetic-pharmacodynamic modeling of the antibacterial activity of Cefpodoxime.  This approach has more detailed information than the MIC about the time course of efficacy (Liu et al, 2005).

    The suprior activity of the third-generation cephalosporins against Enterobacteriaceae is being challenged by the increasing frequency of pathogens with β-lactamase-mediated resistance, such as AMpC B-lactamases, ESBLs and carbapenemases.
