Beta blockers work by blocking the effects of adrenaline, aka slowing your heart rate and reducing those physical signs and symptoms of nervousness and anxiety, he explained.
Beta blockers reduce anxiety by decreasing heart rate and preventing shaking. Beta blockers include propranolol, oxprenolol, and metoprolol. [33] [34] The alpha-1 antagonist prazosin could be effective for PTSD. [35] The alpha-2 agonists clonidine and guanfacine have demonstrated both anxiolytic and anxiogenic effects. [36]
Beta blockers vary in their lipophilicity (fat solubility) and in turn in their ability to cross the blood–brain barrier and exert effects in the central nervous system. [76] Beta blockers with greater blood–brain barrier permeability can have both neuropsychiatric therapeutic benefits and side effects, as well as adverse cognitive effects ...
There is clear evidence from many controlled trials in the past 25 years that beta blockers are effective in anxiety disorders, though the mechanism of action is not known. [3] Some people have used beta blockers for performance type social anxiety, or "stage fright." In particular, musicians, public speakers, actors, and professional dancers ...
Figure 1: The chemical structure of dichloroisoprenaline or dichloroisoproterenol (), abbreviated DCI — the first β-blocker to be developed. β adrenergic receptor antagonists (also called beta-blockers or β-blockers) were initially developed in the 1960s, for the treatment of angina pectoris but are now also used for hypertension, congestive heart failure and certain arrhythmias.

Metoprolol is classified as a moderately lipophilic beta blocker. [37] More lipophilic beta blockers tend to cross the blood–brain barrier more readily, with greater potential for effects in the central nervous system as well as associated neuropsychiatric side effects. [37] Metoprolol binds mainly to human serum albumin with an unbound ...
Although beta-blockers such as propranolol have been suggested to be beneficial in managing physical symptoms of anxiety, its efficacy in treating generalized anxiety disorder and panic disorder remain unestablished. [16] Some experimentation has been conducted in other psychiatric areas: [17] Post-traumatic stress disorder (PTSD) and specific ...
Guanfacine is also used off-label to treat tic disorders, anxiety disorders such as generalized anxiety disorder, and PTSD. [ 24 ] [ 15 ] Guanfacine and other α 2A -adrenergic receptor agonists have anxiolytic -like action, [ 25 ] thereby reducing the emotional responses of the amygdala , and strengthening prefrontal cortical regulation of ...
