Indication: In recent years, many common clinical pathogens often show resistance to this product, so the treatment of bacterial infections needs to refer to the drug sensitivity results. The main indications of this product are the following infections caused by sensitive strains: 1. Urinary tract infections caused by sensitive strains of Escherichia coli, Klebsiella, Enterobacter, Proteus mirabilis, Proteus vulgaris and Morganella. 2. Acute otitis media in children over 2 years old caused by Streptococcus pneumoniae or Haemophilus influenzae. 3. Acute exacerbation of chronic bronchitis in adults caused by Streptococcus pneumoniae or Haemophilus influenzae. 4. Intestinal infections and Shigella infections caused by sensitive strains of Shigella flexneri or sonnei. 5. This product is the first choice for the treatment of Pneumocystis carinii pneumonia. 6. For the prevention of Pneumocystis carinii pneumonia, patients with a history of at least one attack of Pneumocystis carinii disease or HIV-infected adults can use it, whose CD4 lymphocyte count is ≤200/mm3 or less than 20% of the total lymphocyte count. 7. Traveler's diarrhea caused by enterotoxigenic Escherichia coli (ETEC).

Indication: It is suitable for mild and moderate infections caused by sensitive Staphylococci, Streptococci and Streptococcus pneumoniae, such as pharyngitis, tonsillitis, sinusitis, otitis media, periodontitis, acute bronchitis, acute exacerbation of chronic bronchitis, pneumonia, non-gonococcal urethritis, skin and soft tissue infections. It can also be used for cryptosporidiosis or as an optional drug for the treatment of toxoplasmosis in pregnant women.
