Sodium and chloride are important electrolytes in the body, mainly present in extracellular fluid, and play a very important role in maintaining normal blood and extracellular fluid volume and osmotic pressure. Plasma sodium plays a decisive role in osmotic pressure. Sodium and chloride ions in the human body are mainly regulated by the hypothalamus, posterior pituitary gland and kidneys to maintain the stability of body fluid volume and osmotic pressure.

This product can inhibit the synthesis of prostaglandins and has antipyretic, analgesic and anti-inflammatory effects.

①Analgesic effect: It is mainly through inhibiting the synthesis of prostaglandins and other substances that can make pain sensitive to mechanical or chemical stimulation (such as bradykinin, histamine), and it is a peripheral analgesic. However, the possibility of central analgesia (possibly acting on the hypothalamus) cannot be ruled out; ②Anti-inflammatory effect: The exact mechanism is still unclear. It may be due to the fact that this product acts on inflamed tissues and inhibits the synthesis of prostaglandins or other substances that can cause inflammatory reactions (such as histamine) to play an anti-inflammatory role. Inhibition of the release of lysosomal enzymes and leukocyte chemotaxis may also be related to it; ③Antipyretic effect: It may act on the hypothalamic thermoregulatory center to cause peripheral vasodilation, increased skin blood flow, sweating, and increased heat dissipation to play an antipyretic role. This central effect may be related to the inhibition of prostaglandin synthesis in the hypothalamus; ④Anti-rheumatic effect: The anti-rheumatic mechanism of this product, in addition to antipyretic and analgesic effects, is mainly anti-inflammatory; ⑤Inhibition of platelet aggregation: It works by inhibiting platelet cyclooxygenase and reducing the production of prostaglandins.

It has the effects of improving the viscoelasticity of blood rheology, anti-thrombosis, lowering blood viscosity, relieving spasm of micro-arteries and veins, disaggregating red blood cells and platelets, lowering blood lipids, inhibiting the occurrence and development of atherosclerotic lesions, dilating peripheral blood vessels, improving microcirculation, inhibiting the formation of thrombi in arteries and veins, lowering blood sugar and blood pressure.

This product belongs to the macrolide antibiotics. It has antibacterial activity against Staphylococcus (except methicillin-resistant strains), all groups of streptococci and Gram-positive bacilli. Neisseria, Haemophilus influenzae, Bordetella pertussis, etc. are also sensitive to this product. This product also has antibacterial effects on various anaerobic bacteria except Bacteroides fragilis and Fusobacterium. It also has inhibitory effects on Legionella, Campylobacter fetus, certain spirochetes, Mycoplasma pneumoniae, Rickettsia and Chlamydia. This product is an antibacterial agent, but it also has a bactericidal effect on certain bacteria at high concentrations. It can penetrate 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) from binding to the "P" site, and also blocking the self-acceptor site ("A" site) of the polypeptide chain.
