Toxicity of beta-1 blocker will contribute to symptoms including bradycardia, hypotension, due to its extensive blockage of beta-1 receptor. [5] Moreover, overdose of beta-1 blocker may lead to the loss of their selectivity and bind to beta-2 receptor, causing bronchopulmonary symptoms. [5]
Beta blockers interfere with the binding to the receptor of epinephrine and other stress hormones and thereby weaken the effects of stress hormones. Some beta blockers block activation of all types of β-adrenergic receptors and others are selective for one of the three known types of beta receptors, designated β 1, β 2 and β 3 receptors.
Beta 1 blockers are contraindicated in people with complete or second-degree heart block or recent history of fluid retention without using diuretics. [4] Additionally, beta 1 blockers can affect beta 2 receptors, particularly at high doses, and hence should not be administered to patients with peripheral vascular disease or diabetes mellitus ...
Beta blockers are a type of medication used to treat heart conditions and cardiovascular diseases, like congestive heart failure, heart attacks, coronary artery disease (aka when a buncha gunk ...
There is clear evidence from many controlled trials in the past 25 years that beta blockers are effective in anxiety disorders, though the mechanism of action is not known. [3] Some people have used beta blockers for performance type social anxiety, or "stage fright." In particular, musicians, public speakers, actors, and professional dancers ...
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. [7] [8] It is taken by mouth. [7]
Not all beta blockers are the same; some are cardio selective (affecting only beta 1 receptors) while others are non-selective (affecting beta 1 and 2 receptors). Beta blockers that target the beta-1 receptor are called cardio selective because beta-1 is responsible for increasing heart rate; hence a beta blocker will slow the heart rate.
Acebutolol, [1] sold under the brand names Sectral among others, is a beta blocker for the treatment of hypertension and arrhythmias. Acebutolol is a cardioselective beta-1 blocker and has intrinsic sympathetic activity. It is commonly used in the treatment of angina. It was patented in 1967 and approved for medical use in 1973. [2]
