Cyclophosphoglucoside glucosamine can promote calcium ion inward flow, enhance phosphorylation, promote excitation, improve myocardial contractility, and play a positive inotropic effect. It can also reduce myocardial oxygen consumption, nourish myocardium, promote myocardial cell survival, increase myocardial cells, resist ischemia and hypoxia, and resist damage, repair the skin cells of sinus node, improve the function and conduction of sinus node and atrioventricular node, and have anti-arrhythmic effects. It also dilates peripheral blood vessels, reduces the anterior and posterior loads on the heart, increases cardiac blood output, improves cardiac function, dilates bronchial smooth muscle, and plays an important role in the regulation of sugar and fat metabolism, nucleic acid and protein synthesis. It can directly participate in cellular excretion to replenish energy, and inhibit platelet activity to prevent thrombosis. In clinical use can be used in cardiovascular surgery, or major surgery, respiratory medicine, nephrology, etc.
