How Does It Work?

Norvasc is part of a class of drugs called calcium channel blockers. It helps slow down the rate at which calcium moves into your heart and into the blood vessel walls. This, in turn, helps to relax the vessels, which allows better blood flow and causes lower blood pressure. It also makes it easier for the heart to pump blood.
There are two basic types of calcium channel blockers: dihydropyridine and non-dihydropyridine. The most important difference between the two types is that non-dihydropyridine calcium channel blockers can slow down the heart rate, while dihydropyridine calcium channel blockers do not. Norvasc is a dihydropyridine calcium channel blocker, which means that it does not have an effect on heart rate.
