It promotes the synthesis and release of dopamine in the striatum, reduces the reuptake of dopamine by nerve cells, and has an anti-acetylcholine effect, thereby improving the symptoms of Parkinson's disease patients.

By inhibiting the early synthesis of bacterial cell walls, bacterial cell wall synthesis is inhibited, leading to their death

Interfere with bacterial folic acid metabolism, selectively inhibit the activity of bacterial dihydrofolate reductase, prevent dihydrofolate from being reduced to tetrahydrofolate, and prevent the synthesis of bacterial nucleic acids and proteins

Vitamin E is an antioxidant that can combine with selenium in the diet to prevent polyunsaturated fatty acids in membranes and other cell structures from being damaged by free radicals, protect red blood cells from hemolysis, protect nerves and muscles from damage by oxygen free radicals, maintain the normal development and function of nerves and muscles, and may also be a cofactor for certain enzyme systems.

Niacin is converted into nicotinamide in the body, and then combined with riboadenine to form nicotinamide adenine dinucleotide (coenzyme I) and nicotinamide adenine dinucleotide phosphate (coenzyme II), which are necessary for lipid, amino acid, protein, purine metabolism, tissue respiration oxidation and glycogenolysis. Niacin can reduce the utilization of coenzyme A and affect the transport of cholesterol in the blood by inhibiting the synthesis of very low density lipoprotein (VLDL).

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

It has a direct relaxant effect on the smooth muscles of the respiratory tract, which is partly due to the release of endogenous adrenaline and norepinephrine. In addition, theophylline is a purine receptor blocker and can counteract the contraction of adenine and other substances on the respiratory tract. Theophylline can enhance the contraction of the diaphragm, especially when the diaphragm is weak, so it is beneficial to improve respiratory function.

It can directly stimulate adrenaline receptors, or indirectly stimulate adrenaline receptors by inducing the release of norepinephrine from adrenergic nerve endings, and has a stimulating effect on both alpha and beta receptors. It can dilate bronchi and contract local blood vessels to eliminate congestion and swelling of the nasopharyngeal mucosa, and relieve nasal congestion symptoms, with a longer duration of action; it can strengthen myocardial contractility, increase cardiac output, and ensure sufficient venous return to the heart; it has a stronger central nervous system stimulating effect than adrenaline.

Methylephedrine hydrochloride can directly stimulate adrenaline receptors, and can also indirectly stimulate adrenaline receptors by prompting adrenergic nerve endings to release norepinephrine, and has an stimulating effect on both alpha and beta receptors. It can dilate the bronchi and contract local blood vessels to eliminate congestion and swelling of the nasopharyngeal mucosa, relieve nasal congestion symptoms, and has a longer duration of action; strengthen myocardial contractility, increase cardiac output, and make venous return to the heart sufficient; it has a stronger central nervous system excitation effect than adrenaline.
