This product is a brain metabolism improving drug, which is a cyclic derivative of г-aminobutyric acid. It has the effect of resisting brain function damage caused by physical and chemical factors. It can promote the generation of ATP in the brain, promote the synthesis of acetylcholine 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 improving effect on retrograde amnesia caused by hypoxia. It can enhance memory and improve learning ability.

Vasodilators, which can dilate coronary arteries and cerebral blood vessels, reduce myocardial oxygen consumption, improve microcirculation, and inhibit platelet aggregation

It is a blood volume expander. After intravenous injection, it can increase plasma colloidal osmotic pressure, absorb extravascular water to increase blood volume, and increase and maintain blood pressure. Its blood volume expansion effect is stronger than that of dextran 40, and it has almost no effect on improving microcirculation and osmotic diuresis. It can also reduce the activity of certain coagulation factors and platelets, and thus has a certain anti-thrombotic effect. It has strong antigenicity, and some patients may have allergic reactions.

This product is a blood volume expander. After intravenous injection, it can increase plasma colloidal osmotic pressure, absorb extravascular water to increase blood volume, and increase and maintain blood pressure. The increase in plasma volume is related to the amount of dextran input. However, its blood volume expansion effect is stronger than dextran 40, and it has almost no effect on improving microcirculation and osmotic diuresis. In addition, this product can also reduce the activity of certain coagulation factors and platelets, and thus has a certain anti-thrombotic effect. This product has strong antigenicity. Since there are bacteria that produce this product in the normal intestine, some patients will have allergic reactions even after the first injection of this product. Mainly skin and mucous membrane allergic reactions.

This product is a H2 receptor blocker of the guanyl thiazole class, which has the characteristics of high affinity for H2 receptors, and has a significant inhibitory effect on gastric acid secretion, and has an inhibitory effect on basal secretion and the increase of gastric acid and pepsin caused by various stimuli. This product does not change the gastric emptying rate, does not interfere with pancreatic function, and has no adverse effects on the cardiovascular system and kidney function. It is different from cimetidine, but similar to ranitidine, that is, long-term high-dose treatment does not cause adverse reactions of androgen antagonism such as male breast development, impotence, lack of sexual desire, and female breast pain and galactorrhea. It has no teratogenic, carcinogenic, drug enzyme inhibitory and androgen inhibitory effects.

This product is a calcium supplement. Calcium can maintain the normal excitability of nerves and muscles and promote the secretion of acetylcholine by nerve endings. When serum calcium is low, the excitability of nerves and muscles may increase, resulting in convulsions. When blood calcium is too high, the excitability decreases, resulting in weakness, etc. Calcium ions can improve the permeability of cell membranes, increase the density of capillaries, reduce exudation, and have an anti-allergic effect. Calcium ions can promote the calcification of bones and teeth. There is a competitive antagonism between high concentrations of calcium ions and magnesium ions, which can be used to rescue magnesium poisoning; calcium ions can react with fluoride to form insoluble calcium fluoride, which can be used to rescue fluoride poisoning.
