Beta blockers lower your blood pressure and the stress your heart feels. They work in many different ways.
Beta blockers lower your blood pressure by blocking chemicals that can make your heart more active than it needs to be. The main chemical these medicines block is norepinephrine. This is a type of adrenaline. Blocking some of this chemical can make your heart pump slower and with less force. This can result in lower blood pressure.
Some beta blockers such as atenolol and metoprolol reduce how much blood your heart pumps. Other beta blockers such as carvedilol and labetalol help open up your blood vessels. These effects all help lower your blood pressure.
Less stress, less pressure, more health!
