It relaxes vascular smooth muscle, releases nitric oxide (NO) through metabolism to generate isosorbide mononitrate, activates guanylate cyclase, and increases cyclic guanosine monophosphate (cGMP) in smooth muscle cells, thereby relaxing vascular smooth muscle, dilating peripheral arteries and veins, reducing myocardial oxygen consumption, increasing oxygen supply, and relieving angina pectoris.

This product is a disinfectant and preservative. Its mechanism of action is to denature and kill bacterial proteins. It has a killing effect on bacteria, fungi, and viruses.

Sodium glycerophosphate is a phosphorus supplement used to meet the body's daily phosphorus needs. Phosphorus is involved in bone formation and in the composition of cell membranes in the form of phospholipids. Phosphorus is also related to the activity of many metabolic enzymes and plays a vital role in energy metabolism.

The caffeine in this product can increase the intracellular cyclic adenosine monophosphate (cAMP) content. Small doses can enhance the excitement process of the cerebral cortex, invigorate the spirit, and relieve fatigue. Large doses can excite the medulla oblongata center.

Vitamin B1 combines with adenosine triphosphate to form vitamin B1 pyrophosphate, which is a necessary coenzyme for carbohydrate metabolism. Vitamin B1 can inhibit the activity of cholinesterase. When it is deficient, the activity of cholinesterase is enhanced, the hydrolysis of acetylcholine is accelerated, and the conduction of nerve impulses is impaired, affecting gastrointestinal and myocardial functions.

Nicotinic acid can be converted into nicotinamide in the body, and then combined with riboadenin to form nicotinamide adenine dinucleotide (coenzyme I) and nicotinamide adenine dinucleotide phosphate (coenzyme II), which are essential for lipid, amino acid, protein, purine metabolism, tissue respiration oxidation and glycogenolysis. Nicotinic acid can reduce the effect of coenzyme A; it affects the transport of cholesterol in the blood by inhibiting the synthesis of very low density lipoprotein (VLDL). Nicotine also has the effect of peripheral vasodilation.

This product is a penicillin antibiotic, which has good antibacterial activity against Streptococcus such as Streptococcus pneumoniae and hemolytic Streptococcus, aerobic Gram-positive cocci such as non-penicillinase-producing Staphylococcus and Enterococcus faecalis, aerobic Gram-negative bacteria such as Escherichia coli, Proteus mirabilis, Salmonella, Haemophilus influenzae, Neisseria gonorrhoeae, and Helicobacter pylori. Amoxicillin exerts its bactericidal effect by inhibiting the synthesis of bacterial cell walls, which can quickly dissolve and rupture bacteria into spherical bodies.

This product belongs to the macrolide antibiotics, which is the ethyl succinate of erythromycin. It is more stable than erythromycin in gastric acid. It has antibacterial activity against Staphylococcus (except methicillin-resistant strains), various 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, 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 penetrate the bacterial cell membrane and form a reversible bond with 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 displacement of the polypeptide chain from the acceptor site (A site) to the P site, thereby inhibiting bacterial protein synthesis.
