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 ...
The cardio-selective beta-1 blockers could cause adverse effects including bradycardia, reduced exercise ability, hypotension, atrioventricular nodal blockage and heart failure. [5] Other possible adverse effects include nausea and vomiting, abdominal discomfort, dizziness, weakness, headache, fatigue, and dryness in mouth and eye. [5]

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 ...
[22] [23] Metoprolol may also cause the hands and feet to feel cold. [24] Due to the high penetration across the blood–brain barrier, lipophilic beta blockers such as propranolol and metoprolol are more likely than other less lipophilic beta blockers to cause sleep disturbances such as insomnia, vivid dreams and nightmares. [25]
Nightmares can also be triggered by stress and anxiety and substance abuse, such as drugs that affect the neurotransmitters norepinephrine and dopamine and serotonin. Nevertheless, causality between drugs such as beta-blockers or alpha-agonists and nightmares is still unclear and further research needs to be done to investigate the biochemical ...
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]
