The antibacterial property is similar to that of cefazolin, and it has good antibacterial effect on Staphylococcus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, Proteus mirabilis, Haemophilus influenzae, etc.

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 bacillus, and brucella are also very sensitive. Escherichia coli, Salmonella, Shigella dysenteriae, Proteus, influenza bacillus, pneumococci, gonococci, etc. have different degrees of drug resistance because some strains produce beta-lactamase. Among them, the drug 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. It is mainly used to treat infectious diseases caused by sensitive Staphylococcus aureus, hemolytic streptococci, gonococci, meningococci, diphtheria bacillus, pertussis bacillus, influenza bacillus, Salmonella, Shigella, etc.

This product is a broad-spectrum antifungal drug. Its mechanism of action is to inhibit the synthesis of fungal cell membranes and affect their metabolic processes. It has antibacterial effects on dermatophytes, Candida, etc., and also has certain therapeutic effects on certain Gram-positive cocci.

This product is a broad-spectrum antibacterial agent with bactericidal effect at high concentrations. Many Rickettsia, Mycoplasma, Chlamydia, and Spirochete are sensitive to this product, while Enterococcus is resistant to it. Due to the widespread use of tetracyclines over the years, common clinical pathogens are seriously resistant to tetracyclines, including Gram-positive bacteria such as Staphylococcus and most Enterobacteriaceae. There is cross-resistance between this product and different varieties of tetracyclines. The mechanism of action of this product is that the drug can specifically bind to the A position of the 30S subunit of the bacterial ribosome, inhibit the growth of the peptide chain and affect the synthesis of bacterial proteins.

It is a highly effective fluorinated and chlorinated corticosteroid with anti-inflammatory, anti-pruritic and vasoconstrictive effects. Its anti-inflammatory and antipruritic mechanism is to increase the responsiveness of β receptors to catecholamine, increase the production of CAMP by activating adenylate cyclase, and inhibit phosphoethylesterase to reduce the destruction of CAMP, resulting in an increase in the concentration of cAMP in cells and inhibiting the release of histamine. The effect of this product in inhibiting the proliferation of granulomas in rats and mice is similar to that of dexamethasone.
