Beta blockers treat high blood pressure, glaucoma and migraines. Learn more about these drugs.
Beta blockers reduce blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. As a result, the heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers also help blood vessels relax and open up to improve blood flow.
