Beta(β) blockers
Beta(β) blockers, also known as beta-adrenergic blocking agents, are blood pressure medications. The hormone epinephrine, also known as adrenaline, is inhibited by beta blockers.
Beta blockers cause the heart to beat more slowly and forcefully, lowering blood pressure. Beta blockers also aid in the widening of veins and arteries, which improves blood flow.
Examples of beta (β) blockers
- Acebutolol
- Atenolol (Tenormin)
- Bisoprolol (Zebeta)
- Metoprolol (Lopressor, Toprol XL)
- Nadolol (Corgard)
- Nebivolol (Bystolic)
- Propranolol (Inderal, InnoPran XL)
