Chỉ dẫn điều trị:

Nifedipine capsules, USP are indicated for the management of vasospastic angina confirmed by any of the following criteria: 1) classical pattern of angina at rest accompanied by ST segment elevation, 2) angina or coronary artery spasm provoked by ergonovine, or 3) angiographically demonstrated coronary artery spasm. In those patients who have had angiography, the presence of significant fixed obstructive disease is not incompatible with the diagnosis of vasospastic angina, provided that the above criteria are satisfied. Nifedipine may also be used where the clinical presentation suggests a possible vasospastic component but where vasospasm has not been confirmed, e.g., where pain has a variable threshold on exertion or when angina is refractory to nitrates and/or adequate doses of beta blockers. Nifedipine capsules, USP are indicated for the management of chronic stable angina (effort-associated angina) without evidence of vasospasm in patients who remain symptomatic despite adequate doses of beta blockers an

and has the structural
formula:
Nifedipine, USP is a yellow crystalline substance, practically
insoluble in water but soluble

CLINICAL PHARMACOLOGY
Nifedipine is a calcium ion influx inhibitor (slow-channel blocker or
calcium ion antagonist)
and inhibits the transmembrane influx of calcium ions into cardiac
muscle and smooth

muscle. The contractile processes of cardiac muscle and vascular
smooth muscle are
dependent upon the movement of extracellular calcium ions into these
cells through
specific ion channels. Nifedipine selectively inhibits calcium ion
influx across the cell
membrane of cardiac muscle and vascular smooth muscle without changing
serum
calcium concentrations.
MECHANISM OF ACTION:
The precise means by which this inhibition relieves angina has not
been fully determined,
but includes at least the follo
