It has central and peripheral antitussive effects, and its antitussive effect is about 1/3 of that of codeine. In addition to having a direct inhibitory effect on the respiratory center of the medulla oblongata, it also has a mild atropine-like effect. It can relax spasmodic bronchial smooth muscles and reduce airway resistance.

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.

1. Treat metabolic acidosis. This product can increase the concentration of bicarbonate in plasma, neutralize hydrogen ions, and thus correct acidosis. 2. Alkalize urine. When using this product, due to the increase in bicarbonate concentration in urine and the increase in urine pH, uric acid, sulfonamides, and hemoglobin are not easy to form crystals or aggregate in urine. 3. Acid antacid. Oral administration can quickly neutralize or buffer gastric acid without directly affecting gastric acid secretion. Therefore, the pH in the stomach increases rapidly, relieving symptoms caused by high gastric acid. Pharmacokinetics: This product can be excreted by the kidneys in the form of bicarbonate, or it can be excreted from the body by the lungs in the form of carbon dioxide.

Participates in the formation of antibodies and collagen in the body, tissue repair (including certain redox effects), metabolism of phenylalanine, tyrosine, and folic acid, utilization of iron and carbohydrates, synthesis of fat and protein, and maintenance of immune function, hydroxylation of 5-hydroxytryptamine, maintenance of vascular integrity, and promotion of absorption of non-heme iron
