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).

2023年8月22日 · Summarize the mechanism of action of the beta-blocker class of medications, including the difference between selective and non-selective agents. Identify the indications for beta-blocker therapy. Review the adverse events, contraindications, toxicities, and interactions of …

2022年1月18日 · Beta-blockers are a widely used, commonly prescribed class of medications. They can treat a wide range of problems, ranging from high blood pressure and heart problems to preventing migraines and anxiety attacks.

2024年3月5日 · Beta blockers are classified as either selective or non-selective. Selective beta blockers mainly affect the heart. Non-selective beta blockers have effects on the heart and other areas of the body. One beta blocker may be preferred over another in certain situations.

Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms (arrhythmia), and to protect the heart from a second heart attack after a first heart attack (secondary prevention). [1] .

Beta-adrenergic blocking agents are a class of medicines that bind to beta-adrenoreceptors and prevent the binding of norepinephrine and epinephrine at these receptors.

Different Classes of Beta-Blockers and Specific Drugs. Beta-blockers that are used clinically can be divided into two classes: 1) non-selective blockers (block both β 1 and β 2 receptors), or 2) relatively selective β 1 blockers ("cardioselective" beta-blockers). Some beta-blockers have additional mechanisms besides beta-blockade that ...

2025年3月27日 · Beta blockers are medicines that lower blood pressure. They also may be called beta-adrenergic blocking agents. The medicines block the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force. This lowers blood pressure.

2024年11月19日 · Beta-blockers are a class of medication used to block the effects of stress hormones such as adrenaline on the heart. They’re often prescribed for irregular heartbeat, high blood...

Beta blockers, also known as beta-adrenergic blocking agents, are drugs that block norepinephrine and epinephrine (adrenaline) from binding to beta receptors on nerves. Norepinephrine and epinephrine are produced by nerves …
