Mainly stimulates pancreatic beta cells to secrete insulin to produce blood sugar lowering effect

It can reduce the production of glycogen in the liver, reduce intestinal absorption of sugar, and increase insulin sensitivity by increasing peripheral sugar uptake and utilization

It has a direct relaxant effect on the smooth muscles of the respiratory tract. Its mechanism of action includes inhibiting phosphodiesterase to increase the intracellular cAMP content, producing a bronchial dilation effect through the release of endogenous adrenaline and norepinephrine, acting as a purine receptor blocker to counteract the contractile effect of adenine on the respiratory tract, and enhancing the contractility of the diaphragm to improve respiratory function.

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.
