This product is a semi-synthetic penicillin, which is acid-resistant and penicillinase-resistant. It has antibacterial activity against Gram-positive cocci and Neisseria. Its antibacterial activity against enzyme-producing strains of Staphylococcus (including Staphylococcus aureus and coagulase-negative Staphylococci) is stronger than that of oxacillin, but its antibacterial effect against penicillin-sensitive Staphylococci and various streptococci is weaker than that of penicillin, and it is ineffective against methicillin-resistant Staphylococci.

Broad-spectrum semi-synthetic penicillin has a broad-spectrum killing effect on Gram-positive and Gram-negative bacteria. It has a strong antibacterial effect on hemolytic streptococci, pneumococci and non-penicillinase-producing staphylococci, which is similar to or slightly inferior to penicillin. It also has a good antibacterial effect on viridans streptococci, and is better than penicillin on enterococci and Listeria. It has antibacterial effects on Corynebacterium diphtheriae, Bacillus anthracis, Actinomyces, Haemophilus influenzae, Bordetella pertussis, and Neisseria.

Acid-resistant and enzyme-resistant semi-synthetic penicillin has a broad-spectrum killing effect on Gram-positive and Gram-negative bacteria. It is effective against penicillin-resistant Staphylococcus aureus and can make up for the shortcomings of ampicillin used alone.

Acid-resistant and enzyme-resistant semi-synthetic penicillin is effective against penicillin-resistant Staphylococcus aureus. It can make up for the shortcomings of ampicillin used alone and synergistically enhance the antibacterial effect with it.

A broad-spectrum third-generation cephalosporin with a low MIC, very stable to beta-lactamase, widely distributed in body fluids and various organs, with few side effects and good stability. It has strong antibacterial activity against Enterobacteriaceae, and both influenza bacilli and gonococci that produce and do not produce beta-lactamase are highly sensitive to this product. It has stronger antibacterial effects on Escherichia coli, aerogenes, various Proteus species, and influenza bacilli than second-generation cephalosporins. It has stronger activity against gram-positive cocci such as hemolytic streptococci and pneumococci.
