This product is a mucus regulator, which mainly acts on the secretion of bronchial glands, increasing the secretion of low-viscosity salivary mucin and reducing the production of high-viscosity fucoxomucin, thereby reducing the viscosity of sputum and making it easier to cough up. It takes effect quickly after oral administration, and obvious therapeutic effects can be seen within 4 hours of taking it.

This product is a phenothiazine antipsychotic, and its mechanism of action is mainly related to its blocking of dopamine receptors (DA2) in the mesolimbic system and mesocortical pathways. It has a blocking effect on dopamine (DA1) receptors, 5-hydroxytryptamine receptors, M-type acetylcholine receptors, and α-adrenaline receptors. At low doses, it can inhibit dopamine receptors in the medulla oblongata emetic chemoreceptor area, and at high doses, it can directly inhibit the vomiting center, producing a powerful antiemetic effect. It inhibits the body temperature regulation center, lowering the body temperature, which can change with changes in the external environment. It blocks the action of peripheral α-adrenaline receptors, causing blood vessels to dilate, causing a drop in blood pressure, and also has a certain effect on the endocrine system.

A mild peripheral vasodilator with the pharmacological effects of niacin and inositol, it has a lipid-lowering effect; its vasodilatory effect is milder and more lasting than that of niacin, without side effects such as flushing and stomach discomfort; it selectively dilates blood vessels in diseased areas and sensitive areas stimulated by cold; it has the effects of dissolving blood clots, anti-coagulation, anti-fatty liver, and reducing capillary fragility.

This product is an antibacterial drug. Escherichia coli is mostly sensitive to this product, and some strains of Enterobacteriaceae such as Enterobacter aerogenes, Enterobacter cloacae, Proteus, and Klebsiella are sensitive to this product. Aeruginosa is usually resistant to this product. This product has antibacterial effects on Gram-positive bacteria such as Enterococcus. The antibacterial activity of this product is not affected by pus and tissue decomposition products. It is more active in acidic urine. The antibacterial mechanism is to interfere with the oxidoreductase system in the bacteria, thereby blocking its metabolic process.

This product has good antibacterial effect on superficial fungi such as Trichophyton, Microsporum, Epidermophyton, etc. It has no antibacterial effect on Candida, Cryptococcus, Histoplasma, Sporothrix, Blastomyces, Coccidioides, etc. This drug inhibits the growth of fungi by interfering with the synthesis of fungal nucleic acids.
