Product Details:

  • Product Name: Cefixime
  • CAS #: 79350-37-1
  • Mode of Action:

    Like all beta-lactam antibiotics, cefixime binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, causing the inhibition of the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that cefixime interferes with an autolysin inhibitor.

  • Pharmacodynamics:

    Cefixime, an antibiotic, is a third-generation cephalosporin like ceftriaxone and cefotaxime. Cefixime is highly stable in the presence of beta-lactamase enzymes. As a result, many organisms resistant to penicillins and some cephalosporins due to the presence of beta-lactamases, may be susceptible to cefixime. The antibacterial effect of cefixime results from inhibition of mucopeptide synthesis in the bacterial cell wall.

  • Metabolism:

    Hepatic. Approximately 50% of the absorbed dose is excreted unchanged in the urine in 24 hours.

  • Toxicity:

    Symptoms of overdose include blood in the urine, diarrhea, nausea, upper abdominal pain, and vomiting.
