Nifedipine extended-release tablets
Function and Efficacy
Nifedipine (NF) inhibits the influx of calcium ions into cells by blocking the membrane transport of calcium ions in myocardial and vascular smooth muscle, causing decreased 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, oxygen supply to myocardial ischemic sites is increased; by inhibiting the consumption of high-energy phosphate compounds, the ability to resist hypoxia is enhanced.
Ingredients
The main ingredient of this product is nifedipine.
