This product is a penicillin antibiotic. The antibacterial spectrum is the same as penicillin. It has antibacterial activity against most Gram-positive bacteria, Gram-negative cocci, individual Gram-negative bacilli (such as Haemophilus), spirochetes and actinomycetes, but most Staphylococcus strains (90%) including Staphylococcus aureus and coagulase-negative Staphylococci can produce β-lactamase to hydrolyze this product and inactivate it. The activity of this product against most sensitive strains is 2 to 5 times weaker than that of penicillin. It has no antibacterial effect on strains that produce penicillinase. The mechanism of action of this product is to inhibit the synthesis of bacterial cell walls, causing the bacteria to rupture and dissolve rapidly.

It is effective against a variety of Gram-positive and Gram-negative bacteria, acts on the active reproduction stage of bacteria, and has a bactericidal effect by inhibiting the biosynthesis of cell wall mucopeptides.

It is a benzoic acid derivative that competes with ampicillin for the same active transporter in the renal tubules, inhibiting the latter's excretion from the renal tubules, increasing the blood concentration of ampicillin, and prolonging its blood elimination half-life.

This product is a broad-spectrum semi-synthetic penicillin with extremely low toxicity. The antibacterial spectrum is similar to that of penicillin, and it has a strong antibacterial effect on grass-green streptococci, hemolytic streptococci, and enterococci. Diphtheria bacillus, anthrax bacillus, Gram-positive anaerobic cocci and bacilli are sensitive to this product; meningococci, pertussis bacilli, and Brucella are also very sensitive. Escherichia coli, Salmonella, Shigella dysenteriae, Proteus, influenza bacilli, pneumococci, gonococci, etc., all have varying degrees of drug resistance because some strains produce beta-lactamase. Among them, the resistance rate of Escherichia coli is as high as 50-60%. Enterobacter bacteria, Pseudomonas aeruginosa, and anaerobic Gram-negative bacilli are resistant to this product. This product is mainly used to treat infectious diseases caused by sensitive Staphylococcus aureus, hemolytic streptococci, gonococci, meningococci and diphtheria Bordetella, pertussis Bordetella, influenza Bordetella, Salmonella, Shigella, etc.; such as respiratory tract infections (pneumonia, acute and chronic bronchitis, whooping cough, etc.), gastroenteritis and digestive tract infections (liver and gallbladder infections, acute and chronic gastroenteritis, bacillary dysentery, typhoid and paratyphoid, etc.), urinary tract infections (gonorrhea, urethritis, cystitis, etc.), soft tissue infections and sepsis, meningitis, endocarditis, etc.

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.
