Beta blockers and Valium (diazepam) are used to treat anxiety. A difference is beta blockers are usually used to treat high blood pressure and heart problems, and they are prescribed off-label for anxiety. Valium belongs to a different drug class called benzodiazepines that are often prescribed for anxiety. Better Playing Through Chemistry by Blair Tindall, The New York Times, October 17, 2004. (Discusses the use of beta-blockers among professional musicians) Musicians using beta blockers by Blair Tindall. A condensed version of the above article. In Defense of the Beta Blocker by Carl Elliott, The Atlantic, August 20, 2008. (Discusses the use of. For black people and older people, calcium channel blockers might work better than other blood pressure medications, such as beta blockers, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers.
Beta blockers are classified according to the receptors they block.
Non-selective or non-specific beta blockers
First generation beta blockers such as propranolol (and the others listed below) are non-selective or nonspecific. That means they block both beta1 and beta2 receptors and so affect the heart, lungs, vascular smooth muscles, kidneys, GI, etc.
- Propranolol,
- nadolol,
- timolol maleate,
- penbutolol sulfate,
- sotalol hydrochloride, and
- pindolol
Selective or Cardioselective beta blockers
Second generation beta blockers such as Metroprolol and the following block only Beta1 receptors and so mostly affect the heart and cause a reduction in cardiac output:
- Metoprolol (Lopressor, Toprol XL),
- Bisoprolol
- Atenolol
- acebutolol,
- esmolol,
- betaxolol,
Cardioselective beta blockers without intrinsic sympathomimetic activity (ISA) include atenolol, metoprolol, bisoprolol, and practolol. Those
Cardioselective beta blockers with intrinsic sympathomimetic activity (ISA) include celiprolol, acebutolol, and xamoterol. Also, pindolol, penbutolol. Beta-blockers with ISA mimic the effects of epinephrine and norepinephrine and can cause an increase in blood pressure and heart rate. Beta-blockers with ISA don’t reduce the resting cardiac output and heart rate as effectively as Beta-blockers without ISA.

Blockers of both Alpha and Beta- Receptors
Carvedilol selectively antagonizes alpha-1 adrenergic receptors; antagonizes beta-1 and beta-2 adrenergic receptors nonselectively. That is, Carvedilol is a selective alpha and non-selective beta blocker.
Better Blocker Medication
Labetalol selectively antagonizes alpha-1 adrenergic receptors; antagonizes beta-1 and beta-2 adrenergic receptors nonselectively. That is, labetalol is a selective alpha and non-selective beta blocker.
Labetalol and carvedilol work exactly the same way!
