Mechanism of action of beta blockers
Beta blocker - Wikipedia, the free encyclopedia

Beta blockers are known primarily for their reductive effect on heart rate, although this is not the only mechanism of action of importance in congestive heart.

Adverse drug reactions (ADRs) associated with the use of beta blockers include: nausea, diarrhea, bronchospasm, dyspnea, cold extremities, exacerbation of Raynaud's syndrome, bradycardia, hypotension, heart failure, heart block, fatigue, dizziness, alopecia (hair loss), abnormal vision, hallucinations, insomnia, nightmares, sexual dysfunction, erectile dysfunction and/or alteration of glucose and lipid metabolism. Carvedilol therapy is commonly associated with edema. Due to the high penetration across the blood–brain barrier, lipophilic beta blockers, such as propranolol and metoprolol, are more likely than other, less lipophilic, beta blockers to cause sleep disturbances, such as insomnia and vivid dreams and nightmares.

Pharmacology of beta-blocker drugs. Many of the side effects of beta-blockers are related to their cardiac mechanisms and include bradycardia, reduced.

Beta-blockers are used for treating hypertension, angina, myocardial infarction, arrhythmias and heart failure.

Additional details for each drug may be found at www.rxlist.com. The clinical uses indicated in the table represent both on and off-label uses of beta-blockers. 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).

Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When you take beta blockers, the heart.

Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When you take beta blockers, the heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Beta blockers also help blood vessels open up to improve blood flow.

There are three known types of beta receptors, known as beta 1 (β 1 ), beta 2 (β 2 ) and beta 3 (β 3 ). 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.

This action allows the heart to relax and beat more slowly thereby reducing the amount of blood that the heart must pump. Over time, this action improves the pumping mechanism of the heart. When the neurotransmitters are prevented from binding to the receptors, it in turn causes the effects of adrenaline (epinephrine) to be blocked.
