This product is a benzimidazole derivative, which is rapidly metabolized into sulfoxide, sulfone alcohol and 2-amine sulfone alcohol in the body. It selectively and irreversibly inhibits the polymerization of the cytoplasmic microtubule system of the parasite's intestinal wall cells, blocks its absorption of various nutrients and glucose, leads to the depletion of endogenous glycogen in the worm, and inhibits the fumarate reductase system, preventing the production of adenosine triphosphate, making it impossible for the worm to survive and reproduce. Similar to mebendazole, this product can also cause the degeneration of the cytoplasmic microtubules of the worm's intestinal cells, and bind to its tubulin, causing intracellular transport blockage, resulting in the accumulation of Golgi endocrine granules, the gradual dissolution of the cytoplasm, and the complete degeneration of the absorbing cells, causing the death of the worm. This product has the effect of completely killing hookworm eggs and whipworm eggs and partially killing ascarid eggs. In addition to killing and expelling various nematodes parasitic in animals, it also has a significant killing and expelling effect on tapeworms and cysticerci. Toxicological tests show that this product is low in toxicity and safe. The oral LD50 of mice is greater than 800 mg/kg, and the maximum oral tolerance of dogs is above 400 mg/kg. This drug has no effect on the reproductive function of male mice, and has no teratogenic effect on female mice. In female rats and rabbits, when a larger dose (30 mg/kg/day) is used, fetal absorption and bone deformities may occur.

It has a broad spectrum of antimicrobial effects, including aerobic Gram-negative and Gram-positive bacteria, anaerobes, Rickettsia, spirochetes and Chlamydia. It has bactericidal effects on Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis, and only has antibacterial effects on anaerobic bacteria such as Staphylococcus aureus, Streptococcus pyogenes, Streptococcus viridans, Group B hemolytic Streptococcus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhi, Salmonella paratyphi, Shigella, Bacteroides fragilis, etc. Pseudomonas aeruginosa, Acinetobacter, Enterobacter, Serratia marcescens, indole-positive Proteus, methicillin-resistant Staphylococcus and Enterococcus are usually resistant to chloramphenicol. This product is an antibacterial agent that reversibly binds to the 50S subunit of the bacterial ribosome, inhibits peptide chain formation, prevents protein synthesis, and is completely cross-resistant to chloramphenicol. It has a strong immunosuppressive effect, about 6 times stronger than chloramphenicol.

Antibiotic, antibacterial spectrum is similar to erythromycin, mainly has high antibacterial activity against Gram-positive bacteria, its mechanism of action is to inhibit bacterial protein synthesis.

Local anesthetic, external use has analgesic and antipruritic effects.

Cefuroxil is a first-generation oral cephalosporin with good antibacterial effect on most strains of penicillinase-producing and non-penicillinase-producing Staphylococcus aureus, coagulase-negative Staphylococcus, Streptococcus pneumoniae, group A hemolytic Streptococcus, etc. It also has certain antibacterial activity against Escherichia coli, Proteus mirabilis, Salmonella, Shigella, Haemophilus influenzae, and gonococci. Methicillin-resistant Staphylococci, Enterococci, indole-positive Proteus, Enterobacter, Serratia and other Enterobacteriaceae, Pseudomonas aeruginosa, and Bacteroides fragilis are resistant to this product.
