In acute toxicity experiments, the LD50 in mice and rats was greater than 4000 mg/Kg. In subacute toxicity experiments, Wistar male and female rats were given 40 mg, 200 mg and 1000 mg/Kg per day for 5 weeks, and male and female rabbits were given 6 mg, 60 mg and 600 mg/Kg per day for 23 consecutive days. There were no special changes in the blood, urine and morphological observations of the test animals. In chronic toxicity experiments, Wistar male and female rats were given 6 mg, 60 mg and 600 mg/Kg per day for 26 consecutive weeks. There were no special changes in the general state, blood and urine examinations, and morphological observations of the test animals.

This product is a vitamin drug. Vitamin B6 is converted into pyridoxal phosphate in red blood cells and acts as a coenzyme in various metabolic functions of proteins, carbohydrates, and lipids. It also participates in the conversion of tryptophan into niacin or 5-hydroxytryptamine.

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.

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 that 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 can also inhibit the effects of PGE1, bradykinin and histamine, increase the pain threshold and produce analgesic effects.

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
