Jan 18, 2022 · Beta-blockers are beta receptor antagonists, meaning they block beta-adrenergic receptors and slow down certain types of cell activity. What do beta receptors control? Beta receptors come in three different sub-types and have different functions depending on their location.
Mar 5, 2024 · Beta blockers are versatile medications, and there are quite a few to choose from. They’re mainly used to treat heart-related problems, but they can treat other conditions, like migraines and tremors. Most people tolerate beta blockers fairly well, with common side effects fading after a short time. Not all beta blockers work the same way.
Beta blockers are competitive antagonists 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.
Beta blockers, also known as beta-adrenergic blocking agents, are a class of drugs that works by blocking the neurotransmitters norepinephrine and epinephrine from binding to receptors. There are three known types of beta receptors, known as beta 1 (β 1), beta 2 (β 2) and beta 3 (β 3).

Dec 1, 2011 · A number of beta blockers, including atenolol (Tenormin) and metoprolol (Toprol, Lopressor), were designed to block only beta-1 receptors in heart cells. Since they don't affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders.
