    Cefpirome Sulfate Solubilized

    $198.85

    Cefpirome Sulfate Solubilized is a mixture of Cefpirome Sulfate with anhydrous sodium carbonate that is used to stabilize the pH in aqueous solution.  Cefpirome Sulfate is a semisynthetic, broad-spectrum, fourth generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis, and is resistant to β -lactamases.  Cefpirome Sulfate is susceptible to degradation in aqueous solutions and optimal stability is pH 4-6.  Cefpirome Sulfate Solubilized is soluble in water.

    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.  

    The relative lack of cross-resistance between Cefpirome and the third-generation cephalosporins suggests a slightly different mechanism of action of Cefpirome in comparison to the other cephalosporins.

    Due to its compact dipolar structure, Cefpirome can penetrate Gram-negative bacteria more quickly than the other agents (Nikaido et al, 1990).

    Spectrum Cefpirome is a broad-spectrum antibiotic targeting a wide variety of Gram-positive and Gram-negative bacteria. Many Bacteroides, Enterococci, and Haemophilus species have developed resistance to Cefpirome.
    Microbiology Applications Cefpirome 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 effective ranges include:
    • Campylobacter jejuni 0.5 µg/mL – 8 µg/mL
    • Klebsiella pneumoniae 0.032 µg/mL – 0.125 µg/mL
    • Pseudomonas aeruginosa 2 µg/mL 32 µg/m

    Cancer Applications Cefpirome was found to be more effective than ceftazidime, aztreonam, timentin, and piperacillin against nosocomially important isolates during in vitro examination of 253 bacterial isolates from cancer patients (Rolston et al, 1986).
