This product is an amide local anesthetic. After blood absorption or intravenous administration, it has obvious biphasic effects of excitation and inhibition on the central nervous system, and there may be no precursor excitation. When the blood concentration is low, analgesia and drowsiness occur, and the pain threshold increases; with increasing doses, the effect or toxicity increases, and there is an anticonvulsant effect at sub-toxic blood concentrations; convulsions may occur when the blood concentration exceeds 5μg·ml-1. At low doses, it can promote the outflow of K in myocardial cells, reduce the autonomy of the myocardium, and have an anti-ventricular arrhythmia effect; at therapeutic doses, it has no obvious effect on the electrical activity of myocardial cells, atrioventricular conduction, and myocardial contraction; further increases in blood concentrations can cause a slowing of the heart conduction velocity, atrioventricular conduction block, inhibition of myocardial contractility, and a decrease in cardiac output.

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, protect adrenaline from oxidation, enhance the effect of vitamin C and promote its accumulation in the body, maintain vascular elasticity, enhance capillary resistance, and reduce its fragility and permeability.

Maintain vascular elasticity, enhance capillary resistance, reduce its fragility and permeability, promote cell proliferation and prevent blood cell aggregation.

The antipsychotic effect is mainly related to its blocking of dopamine receptors (DA2) in the mesolimbic system and midbrain-cortex pathways related to emotional thinking, while blocking the α-adrenaline receptors in the reticular formation ascending activation system is related to the sedative and tranquilizing effect. This product has a strong antiemetic effect and a weak sedative effect.
