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, and its mechanism is not fully understood. 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.

A broad-spectrum antiviral drug that can inhibit the growth of multiple viruses in vitro. Its mechanism includes inhibiting inosine monophosphate dehydrogenase, influenza virus RNA polymerase and mRNA guanosine transferase, reducing intracellular guanosine triphosphate, and damaging viral RNA and protein synthesis. It may have an immune effect and neutralizing antibody effect on respiratory syncytial virus.

It is a glycoside of dehydrogenated flavonoids, which often coexists with vitamin C in food. It may participate in the action of oxidoreductase in the body, affect the activity of the thyroid gland, and protect adrenaline from oxidation. In the body, it can enhance the effect of vitamin C and promote its accumulation in the body, maintain vascular elasticity, enhance capillary resistance, reduce its fragility and permeability, promote cell proliferation and prevent blood cell aggregation.

Its main pharmacological effects are to maintain vascular elasticity, enhance capillary resistance, reduce its fragility and permeability, promote cell proliferation and prevent blood cell aggregation.

It inhibits the synthesis and release of prostaglandins in the hypothalamus, restores the normal responsiveness of the sensory neurons in the temperature regulation center, and has an antipyretic effect; it has an analgesic effect by inhibiting the synthesis of prostaglandins, etc.; it inhibits the synthesis and release of prostaglandins in the local tissue of inflammation, stabilizes lysosomal enzymes, and affects the phagocytic function of phagocytes, thus playing an anti-inflammatory role

It is a peripheral analgesic. It inhibits the synthesis and release of prostaglandins (PGE1) in the hypothalamic temperature regulation center, causing peripheral vasodilation and sweating to achieve an antipyretic effect; it inhibits the effects of PGE1, bradykinin and histamine, increases the pain threshold and produces analgesic effect.

It is a central nervous system stimulant that can excite the cerebral cortex, increase sensitivity to the outside world, and constrict cerebral blood vessels, thus enhancing the headache relief effects of the first two drugs.

It has a strong histamine H1 receptor blocking effect, can alleviate other respiratory symptoms caused by allergies, and also has a mild inhibitory effect on the central nervous system

Cefazolin is a first-generation cephalosporin with a broad antibacterial spectrum. Except for Enterococcus and methicillin-resistant Staphylococcus, this product has good antibacterial activity against other Gram-positive cocci, and Streptococcus pneumoniae and hemolytic Streptococcus are highly sensitive to this product. Diphtheria Corynebacterium, anthrax Bacillus, Listeria and Clostridium are also very sensitive to this product. This product has good antibacterial activity against some Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae, but has poor antibacterial effect on Staphylococcus aureus. Salmonella typhi, Shigella and Neisseria are sensitive to this product, while other Enterobacteriaceae, Acinetobacter and Pseudomonas aeruginosa are resistant. Enzyme-producing Neisseria gonorrhoeae is resistant to this product; Haemophilus influenzae is only moderately sensitive. Gram-positive anaerobes and some Gram-negative anaerobes are mostly sensitive to this product. Bacteroides fragilis is resistant.
