This product is a semi-synthetic penicillin antibiotic. It has antibacterial effects on Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Proteus, Enterobacter, Citrobacter, Serratia, Acinetobacter, and Gram-positive cocci sensitive to penicillin. It has a bactericidal effect in large doses. Its antibacterial activity against Escherichia coli, Enterobacter, Klebsiella pneumoniae, Citrobacter, Serratia, and Acinetobacter is stronger than carbenicillin and ampicillin; its antibacterial activity against indole-positive Proteus and Pseudomonas aeruginosa is stronger than carbenicillin and sulbenicillin; its antibacterial activity against Gram-positive bacteria such as Staphylococcus aureus is similar to that of carbenicillin, and its antibacterial activity against Streptococcus faecalis is superior to that of carbenicillin and sulbenicillin. It has good antibacterial effect against most anaerobic bacteria such as Bacteroides fragilis.

Amoxicillin is a broad-spectrum penicillin antibiotic, which can be used in combination with potassium clavulanate to protect it from hydrolysis by β-lactamase. It has a good effect on enzyme-producing Staphylococcus aureus, Staphylococcus epidermidis, coagulase-negative Staphylococci and enterococci, and also has good antibacterial activity against certain β-lactamase-producing Enterobacteriaceae, Haemophilus influenzae, Moraxella catarrhalis, Bacteroides fragilis, etc.

Potassium clavulanate itself has only weak antibacterial activity, but it has a strong broad-spectrum β-lactamase inhibitory effect and can protect amoxicillin from β-lactamase hydrolysis.
