Anxiolytics not acting at the benzodiazepine receptor: beta blockers.

Author information

St. Charlesh Hospital, London, U.K.


1. Although there is clear evidence for many controlled trials in the past 25 years that beta blockers are effective in anxiety disorders clear indications for their use are lacking. 2. The balance of evidence suggests that the mechanism of action of beta-blocking drugs is through peripheral blockade of beta-mediated symptoms. 3. Most evidence to the efficacy of beta-blockers comes from study of their use in generalized anxiety and in acute stress. 4. Because beta-blockers carry no risks of pharmacological dependence they may be preferred to many other anti-anxiety drugs.
