The Cleveland Clinic classified beta blockers into two categories, cardioselective and nonselective, according to its website. The latter is for medicines that block the B1 receptors found in the ...
Beta blockers are medications that often prevent paroxysmal and labile hypertension as they interact with the sympathetic nervous system. Beta blockers help reduce blood pressure by blocking the effects of hormone epinephrine, also known as adrenaline. The effect of taking beta blockers can help lower the heart rate as well as help improve the ...
Beta blockers counter this inappropriately high sympathetic activity, eventually leading to an improved ejection fraction, despite an initial reduction in ejection fraction. [citation needed] Trials have shown beta blockers reduce the absolute risk of death by 4.5% over a 13-month period.
While once a first-line treatment for hypertension, the role of beta blockers was downgraded in June 2006 in the United Kingdom to fourth-line, as they do not perform as well as other drugs, particularly in the elderly, and evidence is increasing that the most frequently used beta blockers at usual doses carry an unacceptable risk of provoking ...
Beta-blockers can lower your heart rate and help your heart not work so hard. You might be prescribed a combined alpha- and beta-blocker. Alpha-2 receptor agonists.
In particular, beta-blockers are no longer recommended as first-line treatment due to relative adverse risk of stroke and new-onset of type 2 diabetes when compared to other medications, [3] while certain specific beta-blockers such as atenolol appear to be less useful in overall treatment of hypertension than several other agents.

Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor [7] and used for cardiovascular diseases, [7] including tachyarrhythmias, high blood pressure, angina, and heart failure.
Atenolol is classified as a beta blocker with low lipophilicity and hence lower potential for crossing the blood–brain barrier and entering the brain. [44] This in turn may result in fewer effects in the central nervous system as well as a lower risk of neuropsychiatric side effects. [44] Only small amounts of atenolol are said to enter the ...
