It forms a protective layer in the intestine to prevent the invasion of pathogens and viruses; stimulates the intestine to secrete antibodies and improves intestinal immunity; selectively kills intestinal pathogens, protects and promotes the growth of beneficial bacteria; regulates the electrolyte and water balance of the intestinal mucosa; promotes the secretion of gastric juice and enhances digestive function.

Under acidic conditions, it transforms into an active structure and combines with the SH group of the proton pump ((HK)-ATPase), thereby inhibiting the activity of the enzyme and inhibiting gastric acid secretion; it can inhibit the (HK)-ATPase activity in the microsomes of dog gastric mucosa; it has an inhibitory effect on the acid secretion produced by the stimulation of histamine, acetylcholine and gastrin in the isolated parietal cells of the dog gastric mucosa; it significantly inhibits the acid secretion caused by gastrin or insulin stimulation in healthy adults as well as the nighttime and 24-hour gastric acid secretion; it promotes the healing of chronic gastric and duodenal ulcers in rats; it inhibits gastric, duodenal ulcers and reflux esophagitis in rats caused by various factors.

Zinc is an important component of many enzymes in the body and has the functions of promoting growth and development and improving taste. When it is deficient, growth stagnation, reproductive inability, difficulty in wound healing, body weakness, conjunctivitis, stomatitis, glossitis, lack of appetite, chronic diarrhea, loss of taste and neurological symptoms may occur. Zinc is particularly important for the growth and development of children.

This product belongs to the macrolide antibiotics, which is the dodecyl sulfate of erythromycin propionate. It has antibacterial activity against Staphylococcus, various groups of streptococci and Gram-positive bacilli. Neisseria, Haemophilus influenzae, Bordetella pertussis, etc. may also be sensitive to this product. This product also has antibacterial activity against various anaerobic bacteria except Bacteroides fragilis and Fusobacterium; it also has inhibitory effects on Legionella, Campylobacter fetus, some spirochetes, Mycoplasma pneumoniae, Rickettsia and Chlamydia. This product is an antibacterial agent, but it also has a bactericidal effect on some bacteria at high concentrations. This product can pass through the bacterial cell membrane and reversibly bind to the 50S subunit of the bacterial ribosome near the donor site (P site), blocking the transfer RNA (t-RNA) binding to the P site, and also blocking the displacement of the polypeptide chain from the acceptor site (A site) to the P site, thereby inhibiting bacterial protein synthesis. This product is only effective against bacteria with active division.

This product belongs to Class Ib antiarrhythmic drugs, inhibits the permeability of cell membrane to Na, but does not promote K outflow. It can slow down the conduction of various parts of the cardiac conduction system, reduce membrane reactivity, increase the excitation threshold, prolong the effective adaptation period of the atrium, atrioventricular node, His-Purkinje system (Purkinjes fibers) and ventricle, and block the forward and reverse conduction of the bypass pathway.
