We manufacture Cefixime Tablets Strength : 50 mg / 100 mg / 200 mg TYPICAL USAGE: Infections of respiratory, urinary and biliary tract. Salmonella infection. MECHANISM OF ACTION: 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.
