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 microtubule protein, 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.

Tetracycline antibiotics. This product is a broad-spectrum antibacterial agent. Many Rickettsia, Mycoplasma, Chlamydia, Spirochete, Amoeba and some Plasmodium are also sensitive to this product. Enterococcus is resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, Yersinia, etc. are sensitive to this product. This product has certain antibacterial activity against gonococci and meningococci, but penicillin-resistant gonococci are also resistant to oxytetracycline. Due to the widespread use of tetracyclines over the years, common clinical pathogens have serious resistance to oxytetracycline, including Gram-positive bacteria such as Staphylococcus and most Gram-negative bacteria. There is cross-resistance between different varieties of tetracycline antibiotics.

The first generation of oral cephalosporin has 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 Staphylococcus, Enterococcus, indole-positive Proteus, Enterobacter, Serratia and other Enterobacteriaceae, Pseudomonas aeruginosa and Bacteroides fragilis are resistant to this product.

This product is a synthetic antibacterial anti-tuberculosis drug that can penetrate into mycobacteria to interfere with RNA synthesis, thereby inhibiting bacterial reproduction. It is only effective against mycobacteria in the growth and reproduction period. So far, no cross-resistance has been found between this product and other anti-tuberculosis drugs.
