Beta blockers (sometimes written as β-blockers) are a class of drugs used for various indications, but particularly for the management of hypertension and cardiac arrhythmias. Beta blockers may also be referred to as beta-adrenergic blocking agents, beta-adrenergic antagonists, or beta antagonists.
Pharmacology
Beta blockers block the action of
endogenous catecholamines,
epinephrine (adrenaline) and
norepinephrine (noradrenaline) in particular, on β-
adrenergic receptors, part of the
sympathetic nervous system which mediates the "
fight or flight" response.
There are three known types of beta receptor, designated β1, β2 and β3. β1-Adrenergic receptors are located mainly in the heart, kidney, and adipose tissue. β2-Adrenergic receptors are located mainly in the heart, lung, GI tract, liver, pancreas, and skeletal muscle. The role and location of β3-receptors is less well-defined.
