How Does This Medication Work?

Dilacor XR is part of a class of drugs called

calcium channel blockers. It helps to slow down the rate at which calcium moves into your heart and blood vessel walls. This, in turn, helps to relax blood vessels, which improves blood flow and lowers blood pressure. This 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. Dilacor XR is a non-dihydropyridine calcium channel blocker, which means that it can decrease the heart rate. Because of this, the medication is useful for treating certain types of irregular heart rhythms (arrhythmias).
