Terapeutiske indikationer:

Felodipine extended-release tablets, USP are indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure lowers the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including felodipine. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than 1 drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program’s Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, f

MECHANISM OF ACTION
Felodipine is a member of the dihydropyridine class of calcium channel
antagonists
(calcium channel blockers). It reversibly competes with nitrendipine
and/or other calcium
channel blockers for dihydropyridine binding sites, blocks
voltage-dependent Ca
currents in vascular smooth muscle and cultured rabbit atrial cells,
and blocks
potassium-induced contracture of the rat portal vein.
_In vitro _studies show that the effects of felodipine on contractile
processes are selective,
with greater effects on vascular smooth muscle than cardiac muscle.
Negative inotropic
effects can
