How Do Beta Blockers Work?
Beta blockers work by blocking the effects of the hormone adrenaline, also known as epinephrine.
They cause the heart to beat more slowly and with less force, which lowers blood pressure.
They also help to open blood vessels to improve blood flow.
Some types of beta blockers mainly affect the heart. Others affect both the heart and the blood vessels.
