①. Treat metabolic acidosis. This product increases the concentration of carbonate in plasma and neutralizes hydrogen ions, thereby correcting acidosis. ②. Alkalinize urine. As the pH value increases after the concentration of carbonate in urine increases, uric acid, sulfonamide drugs 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 to relieve the symptoms caused by high gastric acid.

Relaxes smooth muscle; lowers the body temperature of artificially fevered rabbits; has a hypotensive effect on normal and hypertensive animals; dilates coronary arteries, increases coronary blood flow, and reduces vascular resistance; inhibits thrombin-induced 5-HT release from platelets.

This product is a vasodilator that can dilate coronary arteries and cerebral blood vessels, reduce myocardial oxygen consumption, improve microcirculation and resist platelet aggregation.

This product is a macrolide antibiotic, which has an inhibitory effect on Gram-positive bacteria such as Staphylococcus aureus, Streptococcus, and Pneumococcus, as well as some Gram-negative bacteria such as Haemophilus influenzae, Bordetella pertussis, Neisseria gonorrhoeae, Legionella pneumophila, and some anaerobic bacteria such as Bacteroides fragilis, Peptostreptococcus, and Propionibacterium acnes. In addition, it also has an inhibitory effect on mycoplasma. The characteristics of this product are that its antibacterial activity in vitro is similar to that of erythromycin, but its antibacterial activity in vivo against some bacteria such as Staphylococcus aureus, Streptococcus, and Haemophilus influenzae is stronger than that of erythromycin. The mechanism of action of this product is to inhibit the association of the 50S subunit of the nuclear protein and inhibit protein synthesis to produce an antibacterial effect.
