How Does It Work?
Tiazac 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 the 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 is that non-dihydropyridine calcium channel blockers can slow down the heart rate, while dihydropyridine calcium channel blockers do not. Tiazac is a non-dihydropyridine calcium channel blocker, which means that it can decrease the heart rate. As a result, the drug can be useful for treating certain types of irregular heart rhythms (arrhythmias).
