• Factive · Lg Chem Ltd
• Factive · Lg Chem Ltd
• Ceclor
• Ceftin · GSK
  Ceftin works by inhibiting the bacterial enzyme responsible for cell wall synthesis, ultimately leading to bacterial cell death.
• Pipracil
  Pipracil works by inhibiting bacterial cell wall synthesis, ultimately leading to cell lysis and death.
• Amoxil · Generic (originally Beecham/GSK)
  Broad-spectrum aminopenicillin that inhibits bacterial cell wall synthesis by binding penicillin-binding proteins.
• Ciprofloxacine · Poitiers University Hospital
