How Does Nisoldipine Work?
Nisoldipine is part of a class of drugs called
calcium channel blockers. The drug 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 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 the heart rate, while dihydropyridine calcium channel blockers do not. Nisoldipine is a dihydropyridine calcium channel blocker, which means that it does not usually decrease the heart rate.
