Indication: This product can be used to treat infections caused by sensitive strains of microorganisms specified in the following conditions: 1. Lower respiratory system infections: caused by β-lactamase-producing bacteria Haemophilus or Moraxella. 2. Otitis media: caused by β-lactamase-producing bacteria Haemophilus or Moraxella. 3. Sinusitis: caused by β-lactamase-producing bacteria Haemophilus or Moraxella. 4. Skin and skin soft tissue infections: caused by β-lactamase-producing bacteria Staphylococcus, Escherichia coli or Klebsiella. 5. Urinary tract infections: caused by Escherichia coli, Klebsiella or Enterobacter. Although this product is effective for the above infections, infections caused by ampicillin-sensitive bacteria can also be treated with this product because it contains amoxicillin. Therefore, this product is effective for complex infections caused by ampicillin-sensitive microorganisms and β-lactamase-producing microorganisms, and no other antibiotics are needed. Because amoxicillin is more effective than ampicillin and penicillin against Streptococcus pneumoniae in vitro, the vast majority of Streptococcus pneumoniae that are sensitive to ampicillin or penicillin are completely sensitive to amoxicillin and this product. In order to detect the pathogenic bacteria and their sensitivity to this product, bacteriological tests should be performed together with surgical operations. When the infection may involve the above-mentioned microorganisms that produce β-lactamases, treatment must be started before the results of bacteriological and sensitive tests are obtained in order to measure the pathogenic bacteria and their sensitivity to this product. Once the results are known, the treatment plan should be adjusted in a timely manner if necessary.
