Question

what are beta receptors blockes

Answer 1

Beta blockers, also written β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms, and to protect the heart from a second heart attack (myocardial infarction) after a first heart attack (secondary prevention).They are also widely used to treat high blood pressure (hypertension), although they are no longer the first choice for initial treatment of most patients.

Answer 2

Beta blockers are competitiveantagonists that block the receptor sites for the endogenous catecholamines epinephrine (adrenaline) and norepinephrine(noradrenaline) on adrenergic beta receptors, of the sympathetic nervous system, which mediates the fight-or-flight response.
