Pharmacological action

The drug has hypotensive   and antianginal .

Pharmacodynamics and pharmacokinetics

Pharmacodynamics

This drug is a selective blocker (inhibitor) " slow dihydropyridine . It stops the movement of Ca2 + from intracellular space cardiomyocytes   and crates of smooth muscle of the peripheral arteries and heart; at high doses inhibits the output of Ca2 + from intracellular stores.

For therapeutic doses normalizes intercellular Ca2 +, which can be violated in a number of pathological conditions ( hypertension   and others). It has no effect on the tone of veins. It increases coronary blood flow, increases blood flow to ischemic areas   infarction   without the syndrome "steal", stimulates the collaterals. It increases peripheral arteries, reducing the total peripheral resistance, tone infarction, the heart's need for oxygen. It does not affect the atrioventricular   and sinoatrial nodes Has slight antiarrhythmic   action. Also, the drug activates the renal blood flow.

Time of onset of clinical effect Bizkit to 20 minutes, the duration of the effect of -5-6 hours.

In the intestine, it absorbed 90% of the formulation. Bioavailability is about 60%. Receiving food increases the bioavailability. 95% of the drug binds to plasma proteins. The maximum concentration nifedipine   Blood ingestion of two tablets (20 mg of nifedipine) occurs 2-3 hours. Fully converted in the liver.

Excreted by the kidneys in the form of an inert metabolite (70%) in the bile (30%). The half-life is about 3-5 hours.
