Amoxicillin capsule is an oral broad-spectrum semi-synthetic penicillin antibiotic. It is commonly used for respiratory, urinary tract and biliary tract infections caused by sensitive bacteria, as well as typhoid fever. It is suitable for the following infections caused by sensitive bacteria (non-β-lactam-producing strains of mycobacteria): 1, otitis media, sinusitis, pharyngitis, tonsillitis and other upper respiratory tract infections caused by Streptococcus haemolyticus, Streptococcus pneumoniae, Staphylococcus or Haemophilus influenzae. 2, acute bronchitis, pneumonia and other lower respiratory tract infections caused by Streptococcus haemolyticus, Streptococcus pneumoniae, Staphylococcus or Haemophilus influenzae. 3.Urogenital tract infections caused by Escherichia coli, Aspergillus chimaera or Enterococcus faecalis. 4.Skin and soft tissue infections caused by Streptococcus haemolyticus, Staphylococcus or Escherichia coli. 5.Acute simple gonorrhea: typhoid fever, typhoid carriers and leptospirosis. 6, amoxicillin with clarithromycin, H2 receptor antagonist (such as ranitidine, famotidine) or proton pump inhibitor (such as lansoprazole) triplet eradication of gastric, duodenal Helicobacter pylori, reduce gastritis and duodenal bulb ulcer ulcer recurrence rate. Amoxicillin can achieve satisfactory efficacy in the treatment of typhoid fever, other Salmonella spp. infections and typhoid carriers, and its clinical results, bacterial clearance rate and temperature response in the treatment of typhoid fever are better than those of chloramphenicol; it can also achieve satisfactory efficacy in the treatment of urinary tract infections caused by sensitive bacteria, and a single dose of 3g can achieve satisfactory efficacy in patients whose infections are limited to the lower urinary tract. It can be used for infections of the five organs, skin and soft tissues caused by Streptococcus pneumoniae, Staphylococcus aureus which does not produce penicillinase, Streptococcus haemolyticus and Haemophilus influenzae.
