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 ...
What is a beta blocker? Churchwell said the drug class slows the heart by inhibiting and binding to beta one and beta two receptors on the heart. They limit the production of epinephrine ...
The β-blockers are an immensely important class of drugs due to their high prevalence of use. The discovery of β-blockers reaches back to more than 100 years ago, when early investigators came up with the idea that catecholamines were binding selectively to receptor-like structures and that this was the cause of their pharmacological actions.

It is lipid soluble and also has sodium channel-blocking effects. Propranolol is a non-selective β-adrenergic receptor antagonist, or beta blocker; [61] that is, it blocks the action of epinephrine (adrenaline) and norepinephrine (noradrenaline) at both β 1-and β 2-adrenergic receptors.
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.
The first beta blocker, propranolol, was introduced in the early 1960s by the winner of The Nobel Prize in Physiology or Medicine 1988- Sir James W. Black. [23] The drug was originally developed in order to induce a calm effect on the heart by blocking the beta receptor for adrenaline, treating a range of cardiovascular disorders .
ADRB-1 antagonists are a class of drugs also referred to as Beta Blockers β1-selective antagonists are used to manage abnormal heart rhythms and block the action of substances like adrenaline on neurons, allowing blood to flow more easily which lowers blood pressure and cardiac output. They may also shrink vascular tumors.
The findings indicate the drugs could be considered as a way to manage aggression and hostility in people with psychiatric conditions.
