Broad-spectrum antiviral drug. It has the effect of inhibiting the growth of multiple viruses such as respiratory syncytial virus, influenza virus, hepatitis A virus, adenovirus, etc. in vitro. After entering the virus-infected cells, the drug is rapidly phosphorylated, and its product acts as a competitive inhibitor of viral synthase, inhibiting inosine monophosphate dehydrogenase, influenza virus RNA polymerase and mRNA guanosine transferase, thereby causing a decrease in intracellular guanosine triphosphate, impairing viral RNA and protein synthesis, and inhibiting viral replication and transmission. It may also have an immune effect and neutralizing antibody effect on respiratory syncytial virus.

Amikacin sulfate is an aminoglycoside antibiotic that has antibacterial effects on most Enterobacteriaceae, Pseudomonas aeruginosa, some other Pseudomonas, Acinetobacter, Alcaligenes, meningococci, gonococci, influenza bacilli, Yersinia, Campylobacter fetus, Mycobacterium tuberculosis and some Mycobacterium. Its antibacterial activity is slightly lower than that of gentamicin, but it is stable to the aminoglycoside inactivating enzymes produced by many intestinal Gram-negative bacilli. The mechanism of action is to act on the 30S subunit of the bacterial ribosome and inhibit bacterial protein synthesis. Combination with semi-synthetic penicillins or cephalosporins often achieves a synergistic antibacterial effect.

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.

Caffeine can increase the content of cyclic adenosine monophosphate (cAMP) in cells. Small doses can enhance the excitation 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.
