These drugs occupy the adrenergic receptor site so released norepinephrine can be prevented from activating the receptor. Adrenergic antagonists have varying degrees of specificity and are therefore classified into five: nonselective adrenergic antagonists, nonselective alpha- and beta As such there are a lot of antihypertensive drugs that target adrenergic receptors.Adrenergic signalling in the SA node increases the heart rate, so antagonists for beta-1 receptors exert a negative chronotrophic effect they lower the heart rate. Adrenergic blocking agents. Adrenergic receptor-activating drugs.Mechanism of Action: In general, all beta-adrenergic antagonists compete with adrenergic neurotransmitters (i.e catecholamines) for binding at sympathetic receptor sites.

These receptor subtypes regulate all the activity of G proteins (influencing the 2nd messenger system) Adrenergic Blocking Drugs: Sympatholytics- These are mostly competitive " antagonists" of either alpha or beta adrenergic receptors "AKA" (adrenoceptors). Beta-blockers are drugs that bind to beta-adrenoceptors and thereby block the binding of norepinephrine and epinephrine to these receptors.Propranolol was the first clinically useful beta adrenergic receptor antagonist. Drugs which inhibit beta adrenergic receptors are called beta -blocking agents and also beta-blockers.It is possible that beta-blockers having alpha-1 antagonist effect like carvedilol, are more appropriate in this indication.

"Functional studies of the first selective beta 3-adrenergic receptor antagonist SR 59230A in rat brown adipocytes".Beta1-adrenergic agonists, also known as Beta1-adrenergic receptor agonists, are a class of drugs that bind selectively to the beta-1 adrenergic receptor. An adrenergic antagonist is a drug that inhibits the function of adrenergic receptors. There are five adrenergic receptors, which are divided into two groups. The first group of receptors are the beta () adrenergic receptors.
