It is a medium-acting sulfonamide drug that competitively inhibits dihydrofolate synthase, reduces bacterial folate synthesis, and thus inhibits bacterial growth and reproduction. It has antibacterial effects on non-enzyme-producing Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, etc.

When used in combination with sulfonamides, it enhances the antibacterial effect, inhibits the production of tetrahydrofolate by inhibiting bacterial dihydrofolate reductase, affects bacterial nucleic acid synthesis, and inhibits bacterial growth and reproduction. It has antibacterial effects on non-enzyme-producing Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, etc.

This product is a broad-spectrum antibacterial agent with bactericidal effect at high concentrations. In addition to common Gram-positive bacteria, Gram-negative bacteria and anaerobic bacteria, most Rickettsia, Mycoplasma, Chlamydia, atypical mycobacteria and spirochetes are also sensitive to this product. This product is better than Gram-positive bacteria for Gram-negative bacteria, but Enterococcus is resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, etc. are sensitive to this product. This product has certain antibacterial activity against Neisseria gonorrhoeae, but penicillin-resistant gonococci are also resistant to tetracycline. This product has good antibacterial effect on Gram-negative bacteria such as Vibrio, Yersinia pestis, Brucella, Campylobacter, Yersinia, etc., has no antibacterial activity against Pseudomonas aeruginosa, and has certain antibacterial effect on some anaerobic bacteria.

Dopamine 2 (D2) receptor antagonist, 5-hydroxytryptamine 4 (5-HT4) receptor agonist, mildly inhibits 5-HT3 receptors, acts on dopamine receptors in the medullary chemotactic zone (CTZ) to increase the threshold of CTZ, and has a central antiemetic effect; blocks hypothalamic dopamine receptors, promotes prolactin secretion, and has a certain lactation effect; has a prokinetic effect on the upper gastrointestinal tract, increasing the tension and contraction amplitude of the lower esophageal sphincter.

This product is a penicillin antibiotic, which has good antibacterial activity against Streptococcus such as Streptococcus pneumoniae and hemolytic Streptococcus, aerobic Gram-positive cocci such as non-penicillinase-producing Staphylococcus and Enterococcus faecalis, aerobic Gram-negative bacteria such as Escherichia coli, Proteus mirabilis, Salmonella, Haemophilus influenzae, Neisseria gonorrhoeae, and Helicobacter pylori. Amoxicillin exerts its bactericidal effect by inhibiting the synthesis of bacterial cell walls, which can quickly dissolve and rupture bacteria into spherical bodies.

This product has the function of regulating autonomic nervous system dysfunction and endocrine balance disorders.
