PHARMACHOLOGIC EFFECT

Selective calcium channel blocker II class.
It has antihypertensive, antianginal, antispasmodic and vasodilating effect. It blocks the flow of calcium ions into the cells of the smooth muscles of the vessels.
The mechanism of antihypertensive action is due to a direct relaxing effect on smooth muscle vessels.

The antianginal effect of the drug is associated with its ability to expand peripheral arterioles, which leads to a decrease in OPSS.
Reducing the load leads to a decrease in myocardial oxygen demand. On the other hand, under the action of the drug due to the expansion of the coronary arteries, the intake of oxygen increases (especially with angiospastic angina).
The drug does not adversely affect the lipid composition of blood plasma.
Has antiatherosclerotic, antithrombotic activity, increases the rate of glomerular filtration, has a mild natriuretic effect. When diabetic nephropathy does not increase the severity of microalbuminuria.
