By blocking the membrane transport of calcium ions in myocardial and vascular smooth muscle, inhibiting the influx of calcium ions into cells, it causes a decrease in myocardial contractility and vasodilation. Animal experiments have shown that by reducing myocardial contractility and peripheral vascular resistance, myocardial oxygen consumption is reduced; by dilating coronary vessels and developing collateral circulation, the oxygen supply to myocardial ischemic sites is increased; by inhibiting the consumption of high-energy phosphate compounds, the ability to resist hypoxia is enhanced.

This product is a brain metabolism improving drug, which is a cyclic derivative of g-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 positively 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.

This product is a competitive angiotensin converting enzyme inhibitor, which prevents angiotensin I from being converted into angiotensin II, thereby reducing peripheral vascular resistance and reducing water and sodium retention by inhibiting aldosterone secretion. This product can also dilate peripheral blood vessels by interfering with the degradation of bradykinin. For patients with heart failure, this product can also reduce capillary wedge pressure and pulmonary vascular resistance, increase cardiac output and exercise tolerance time.
