Constricted blood vessels increase peripheral resistance and raise blood pressure. Calcium channel blockers work in several ways to lower blood pressure. The main way is by preventing calcium from entering smooth muscle cells in blood vessels, especially small arteries. With less calcium entering these smooth muscle cells, they are more relaxed, dilating (widening) the blood vessels.
