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. It 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.

It can directly stimulate adrenaline receptors, and can also indirectly stimulate adrenaline receptors by prompting adrenaline nerve endings to release norepinephrine. It has a stimulating effect on both alpha and beta receptors. It can dilate bronchi and constrict local blood vessels, and its action time is longer; it strengthens myocardial contractility, increases cardiac output, and makes venous return to the heart sufficient; it has a stronger central nervous system stimulating effect than adrenaline.

It has ① antihistamine effect, which can compete with histamine released from tissues for H1 receptors on effector cells, thereby stopping allergic reactions; ② at the same time, it inhibits central nervous system activity and causes sedative and hypnotic effects; ③ it enhances the effect of antitussive drugs.

Non-narcotic antitussive drugs mainly block the afferent sensory nerve impulses of the lung and pleural receptors, and also directly inhibit the antitussive center. It also has a papaverine-like smooth muscle spasmolytic effect

This product is a gastrin receptor antagonist, which can significantly inhibit the secretion of gastric acid and pepsin caused by gastrin, increase the content of hexosamine in the gastric mucosa, promote glycoprotein synthesis, and protect and promote the healing of the gastric mucosa; it has a choleretic effect, including stimulating bile acid-independent bile secretion, changing the stone-forming factors in bile, and inhibiting the gallbladder contraction-promoting effect of endogenous CCK by antagonizing CCK.
