This product has a broad-spectrum antibacterial effect and strong antibacterial effect. It has strong antibacterial activity against most Enterobacteriaceae, such as Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, and Gram-negative bacteria such as Haemophilus influenzae, Legionella pneumophila, and Neisseria gonorrhoeae. It also has antibacterial effects on Gram-positive bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, and Mycoplasma pneumoniae and Chlamydia pneumoniae, but has poor effects on anaerobic bacteria and enterococci. Its mechanism of action is to inhibit the activity of bacterial DNA gyrase, prevent the synthesis and replication of bacterial DNA, and cause bacterial death.

This product is a second-generation sulfonylurea antidiabetic drug. Its main function is to stimulate the secretion of insulin by pancreatic islet cells. It specifically binds to the sulfonylurea receptors on the cell membrane, closes the K channel, opens the Ca2 channel, increases the intracellular Ca2, and promotes insulin secretion. In addition, it has extrapancreatic effects, including improving the insulin resistance of peripheral tissues (such as liver, muscle, and fat).

Cefepime is a broad-spectrum fourth-generation cephalosporin that achieves bactericidal effects by inhibiting the biosynthesis of bacterial cell walls. In vitro tests have shown that this product is effective against both Gram-positive and Gram-negative bacteria. This product has low affinity for beta-lactamase encoded by bacterial chromosomes, is highly resistant to hydrolysis by most beta-lactamases, and can quickly penetrate into the cells of Gram-negative bacteria. In bacterial cells, its target molecule is penicillin-binding protein (PBP).

Cefazolin is a first-generation cephalosporin with a broad antibacterial spectrum. Except for Enterococcus and methicillin-resistant Staphylococcus, this product has good antibacterial activity against other Gram-positive cocci, and Streptococcus pneumoniae and hemolytic Streptococcus are highly sensitive to this product. Diphtheria Corynebacterium, anthrax Bacillus, Listeria and Clostridium are also very sensitive to this product. This product has good antibacterial activity against some Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae, but has poor antibacterial effect on Staphylococcus aureus. Salmonella typhi, Shigella and Neisseria are sensitive to this product, while other Enterobacteriaceae, Acinetobacter and Pseudomonas aeruginosa are resistant. Enzyme-producing Neisseria gonorrhoeae is resistant to this product; Haemophilus influenzae is only moderately sensitive. Gram-positive anaerobes and some Gram-negative anaerobes are mostly sensitive to this product. Bacteroides fragilis is resistant.

Adefovir dipivoxil is an oral antiviral drug. It is metabolized to adefovir in the body and further phosphorylated to the active metabolite adefovir diphosphate. It inhibits HBV DNA polymerase (reverse transcriptase) by competing with the natural substrate deoxyadenosine triphosphate and causing DNA chain elongation termination after integration into viral DNA. The inhibition constant (Ki) for HBV DNA polymerase is 0.1μM, and the inhibitory effect on human DNA polymerase α and γ is weak.
