How do calcium channel blockers work for high blood pressure?

ANSWER

To treat blood high blood pressure, calcium channel blockers (sometimes called CCBs for short, or calcium antagonists) don't let calcium into certain muscle cells in your heart and blood vessels, so it's harder for electrical signals to pass. Some CCBs keep blood vessels from tightening. Others slow your heart rate or make your heart ease up on how hard it squeezes to push blood.
