Do beta blockers block beta-1 or 2?

First generation beta blockers such as propranolol (Inderal, InnoPran), nadolol (Corgard), timolol maleate (Blocadren), penbutolol sulfate (Levatol), sotalol hydrochloride (Betapace), and pindolol (Visken) are non-selective in nature, meaning that they block both beta1 (β1) and beta2 (β2) receptors and will …

What are beta-1 blockers?

Beta-1 selective blockers are a subclass of beta blockers that are commonly used to treat high blood pressure. Drugs in this class include atenolol (Tenormin), metoprolol (Lopressor), nebivolol (Bystolic) and bisoprolol (Zebeta, Monocor).

Is propranolol beta-1 or Beta 2?

Introduction. Propranolol is a nonselective, competitive antagonist at beta adrenergic receptors. It binds with high affinity to both beta-1 and beta-2 receptor subtypes, but has lower affinity at the beta-3 subtype.

What is the difference between beta blocker 1 and 2?

The two main beta receptors that are targeted by beta blockers are the beta 1 receptor and the beta 2 receptor. A large number of beta 1 receptors are present on the heart and kidney cells, while the beta 2 receptor is the predominant regulator of vascular and nonvascular smooth muscles.

What are the different types of beta blockers?

Beta-blockers can be grouped into those that are non-selective (block both beta-1 and beta-2 receptors, such as nadolol, penbutolol, pindolol, propranolol, sotalol, and timolol), and those that are cardioselective (only block beta-1 receptors, and include acebutolol, betaxolol, bisoprolol, esmolol,…

Are there any cardio selective beta 1 blockers?

The cardio-selective beta-1-blockers include atenolol, betaxolol, bisoprolol, esmolol, acebutolol, metoprolol, and nebivolol. FDA approved uses of beta-1-selective blockers include hypertension, chronic stable angina, heart failure, post-myocardial infarction, and decreased left ventricular function after a recent myocardial infarction.

Which is the best beta blocker to take by mouth?

Examples of beta blockers taken by mouth include: 1 Acebutolol (Sectral) 2 Atenolol (Tenormin) 3 Bisoprolol (Zebeta) 4 Metoprolol (Lopressor, Toprol XL) 5 Nadolol (Corgard) 6 Nebivolol (Bystolic) 7 Propranolol (Inderal, InnoPran XL)

Why are beta blockers used after a heart attack?

They may be used following a myocardial infarction (heart attack) to improve survival rates. Blocking of beta-receptors, especially by nonselective beta-blockers, may cause bronchial constriction (narrowing of the airways).
