Broad-spectrum penicillin antibiotics, when used in combination with potassium clavulanate, can be protected from β-lactamase hydrolysis. It has good effects 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.

It has only weak antibacterial activity itself, but has a strong broad-spectrum β-lactamase inhibitory effect, which can protect amoxicillin from β-lactamase hydrolysis.

This product is a fluoroquinolone antibacterial drug with a broad-spectrum antibacterial effect, especially against aerobic Gram-negative bacteria. It acts on the A subunit of bacterial DNA helicase, inhibits DNA synthesis and replication, and causes bacterial death. It has effects on both Gram-positive and Gram-negative bacteria. Bacteria are not easy to develop resistance to this product, and there is no cross-resistance between similar drugs and antibiotics.

Ampicillin sodium is a broad-spectrum semi-synthetic penicillin. This product has a strong antibacterial effect on hemolytic streptococci, Streptococcus pneumoniae and non-penicillinase-producing Staphylococci, which is similar to or slightly inferior to penicillin. Ampicillin also has a good antibacterial effect on viridans streptococci, and is better than penicillin on enterococci and Listeria. This product has antibacterial activity against Corynebacterium diphtheriae, Bacillus anthracis, Actinomyces, Haemophilus influenzae, Bordetella pertussis, Neisseria and anaerobic bacteria except Bacteroides fragilis. Some Proteus mirabilis, Escherichia coli, Salmonella and Shigella are sensitive to this product. Ampicillin exerts its bactericidal effect by inhibiting bacterial cell wall synthesis.

It has a strong antibacterial effect on hemolytic streptococci, Streptococcus pneumoniae and non-penicillinase-producing Staphylococci. It also has a good antibacterial effect on viridans streptococci. Its effect on Enterococci and Listeria is better than penicillin. It is also effective against Corynebacterium diphtheriae, Bacillus anthracis, Actinomyces, Haemophilus influenzae, Bordetella pertussis, Neisseria, etc.

Acid-resistant and enzyme-resistant semi-synthetic penicillin, effective against penicillin-resistant Staphylococcus aureus. When used in combination with ampicillin sodium, they can enhance each other's effects and make up for the shortcomings of using it alone.
