Käyttöaiheet:

Nifedipine Extended-release Tablet is 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 Extended-release Tablet 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 in unstable angina where electrocardiographic findings are compatible with intermittent vasospasm, or when angina is refractory to nitrates and/or adequate doses of beta-blockers. Nifedipine Extended-release Tablet is indicated for the management of chronic stab

blockers. Nifedipine is 3, 5-pyridinedicarboxylic acid, 1,
4-dihydro-2, 6-dimethyl-4-(2-nitrophenyl)-,
dimethyl ester, C
H N O and has the structural formula:
Nifedipine is a yellow crystalline substance, practically insoluble in
water but soluble in ethanol. It has

SYSTEM COMPONENTS AND PERFORMANCE
Nifedipine Extended-release Tablet is similar in appearance to a
conventional tablet. It consists,
however, of a semipermeable membrane surrounding an osmotically active
drug core. As water from
the gastrointestinal tract enters the tablet, pressure increases in
the core of the tablet, releasing drug
through the precision laser-drilled tablet orifice in the one side of
the tablet.
Nifedipine Extended-release Tablet is designed to provide nifedipine
at an approximately constant rate
over 24 hours. This controlled rate of drug delivery into the
gastrointestinal lumen is independent of pH
or gastrointestinal motility.
Nifedipine Extended-release Tablet depends for its action on the
existence of an osmotic gradient
between the contents of the tablet core and fluid in the GI tract.
Drug delivery is essentially constant as
long as the osmotic gradient remains constant, and then gradually
falls to zero. Upon swallowing, the
