This product is a first-generation cephalosporin, which has good antibacterial effect on some strains of Gram-positive cocci such as non-penicillinase-producing and penicillinase-producing Staphylococcus aureus, coagulase-negative Staphylococcus, group A hemolytic Streptococcus, Streptococcus pneumoniae and viridans Streptococcus. Anaerobic Gram-positive bacteria are mostly sensitive to this product, and Bacteroides fragilis is resistant to this product. Methicillin-resistant Staphylococci and Enterococci are resistant to this product. The effect of this product on Gram-positive and Gram-negative bacteria is similar to that of cephalexin. This product has a certain effect on Neisseria gonorrhoeae, and is also active against enzyme-producing Neisseria gonorrhoeae; its activity against Haemophilus influenzae is poor.

Amoxicillin is a penicillin antibiotic that has good antibacterial activity against Streptococcus such as Streptococcus pneumoniae and hemolytic Streptococcus, aerobic Gram-positive cocci such as non-penicillinase-producing Staphylococci 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.

Relax vascular smooth muscle, reduce myocardial oxygen consumption, increase oxygen supply, and relieve angina. It activates guanylate cyclase by releasing nitric oxide (NO), increasing cyclic guanosine monophosphate (cGMP) in smooth muscle cells, thereby relaxing vascular smooth muscle, dilating peripheral arteries and veins, reducing preload and afterload, and dilating coronary arteries to increase coronary perfusion.
