Beta blockers, also known as beta-adrenergic blockers
The most commonly used beta-blockers in Marfan patients are propranolol (Inderal) and atenolol (Tenormin). Patients who are allergic to beta-blockers may be given a calcium blocker such as verapamil.
Beta blockers are used to reduce or slow down the heart rate by blocking the effect of the hormone adrenaline.
Beta blockers can decrease the myocardial contractility and make heart failure worse. However, beta-blockers were shown to reduce mortality and morbidity in heart failure patients. This may be due to how they can block the damaging effects of sympathetic activity which is too active. Usually, beta-1 selective blockers such as carvedilol are used. Beta blockers should be used in all patients with stable heart failure with reduced LVEF. They should be used after ACE inhibitors.
Eye drop forms of beta blockers, such as timolol (Timoptic), used to treat glaucoma.
Beta blockers work by blocking the hormone epinephrine, also called adrenaline. By doing this, beta blockers cause the heart to beat more slowly.
No they are not.
Beta-blockers are used to block the effects of adrenaline on peripheral tissues, as adrenergic systems are unregulated in hyperthyroidism. This affords symptomatic but temporary relief.

No. Beta blockers slow the heart rate and only affect the heart and how fast it pumps.
They are not. Alpha blockers are given first because beta blockers without prior alpha blockade can cause a hypertensive crisis.
