It can significantly inhibit the basal gastric acid secretion during the day and night, and can also inhibit the gastric acid secretion induced by food, histamine, pentagastrin, caffeine and insulin.

This product is a macrolide antibiotic. Its mechanism of action is similar to that of erythromycin, and its antibacterial spectrum is also similar to that of erythromycin, but its antibacterial activity against most Gram-positive bacteria is slightly worse. Some erythromycin-resistant Staphylococcus aureus are still sensitive to kitasamycin. This product also has considerable activity against diphtheria, tetani, Neisseria gonorrhoeae, pertussis, Rickettsia and Chlamydia trachomatis.

The antibacterial spectrum is similar to that of rifampicin. It has good antibacterial activity against tuberculosis and leprosy. When the dosage is 1/3 of that of rifampicin, similar or higher efficacy can be achieved. It has a good effect on Staphylococcus aureus and has certain antibacterial activity against some Escherichia coli. In addition, it also has an inhibitory effect on Chlamydia trachomatis.

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.
