This product is a brain metabolism improving drug, which has the effect of resisting brain function damage caused by physical and chemical factors. It can promote ATP in the brain, promote acetylcholine synthesis and enhance the conduction of nerve excitement, and has the effect of promoting brain metabolism. It can resist brain function damage caused by physical and chemical factors. It has an improvement effect on retrograde amnesia caused by hypoxia. It can enhance memory and improve learning ability.

1. Pharmacology This product is a brain metabolism improving drug. Piracetam is a cyclic derivative of γ-aminobutyric acid. It has the effect of resisting brain function damage caused by physical and chemical factors. It can promote ATP in the brain, promote acetylcholine synthesis and enhance the conduction of nerve excitation, and has the effect of promoting brain metabolism. It can resist brain function damage caused by physical and chemical factors. It has an improvement effect on retrograde amnesia caused by hypoxia. It can enhance memory and improve learning ability. 2. Toxicology The acute toxicology experiment of animal experiment showed that the oral gavage dose of mice was greater than 10g/Kg, and no death was found. The median lethal dose LD50 of intravenous administration was 9.2g/Kg. Subacute and chronic toxicology experiments did not find any adverse effects on the growth and development of rats and dogs. It has no effect on important internal organs and functions such as blood, heart, liver, kidney, and brain.

It promotes brain metabolism and improves brain circulation by reducing cerebrovascular resistance and increasing cerebral blood flow. It also enhances the function of the ascending activation system of the brainstem reticular structure, the function of the pyramidal system, improves motor paralysis, and has a certain effect on promoting the recovery of brain function and awakening.

1. Increase the sensitivity of peripheral tissues to insulin and increase insulin-mediated glucose utilization; 2. Increase the utilization of glucose by non-insulin-dependent tissues; 3. Inhibit hepatic gluconeogenesis and reduce hepatic glucose output; 4. Inhibit the uptake of glucose by intestinal wall cells; 5. Inhibit the biosynthesis and storage of cholesterol and reduce blood triglyceride and total cholesterol levels.

This product belongs to Class Ic antiarrhythmic drugs, which can reduce the depolarization effect during contraction, prolong conduction, action potential duration and effective refractory period, increase the threshold potential of myocardial cells, and reduce spontaneous excitability of the myocardium; it acts on the atria, ventricles and Purkinje fibers, affecting the formation and conduction of excitation; it has membrane stabilizing effects and competitive β-blocking effects, weak calcium antagonism, mild myocardial inhibition, antihypertensive and heart rate slowing effects; it can also relax coronary artery and bronchial smooth muscles, and has a local anesthetic effect similar to procaine.
