Uses:
Nifedipine
also known as Xintongding, Lixinping and Nifedipine, is a dihydropyridine calcium antagonist that inhibits the uptake of Ca2+ by myocardial and vascular smooth muscles, dilates coronary arteries, increases coronary blood flow, and improves myocardial function. Ischemic tolerance, at the same time can expand the surrounding small arteries, reduce peripheral vascular resistance, relieve coronary spasm, increase coronary flow, improve myocardial hypoxia, and thus lower blood pressure.
Packing and storage:
In 25kg, 50kg, 1000kg net bags, store at a cool, dry and well ventilated place.
