What is a beta-1 selective?

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 Acebutolol beta-1 selective?

The cardio-selective beta-blockers include atenolol, betaxolol, bisoprolol, esmolol, acebutolol, metoprolol, and nebivolol [1].

What do beta-1 blockers do?

Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. Beta blockers cause the heart to beat more slowly and with less force, which lowers blood pressure.

What do beta-1 and beta 2 blockers do?

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 is the most selective beta blocker?

Nebivolol is a lipophilic beta reseptor blocker of third generation with distinct beta-1 with selective and vasodilating properties.

How long can you stay on beta-blockers?

Guidelines recommend beta blocker therapy for three years, but that may not be necessary. Beta blockers work by blocking the effects of the hormone epinephrine, also called adrenaline.

Can you eat bananas with beta-blockers?

People taking beta-blockers should therefore avoid taking potassium supplements, or eating large quantities of fruit (e.g., bananas), unless directed to do so by their doctor.

Why are beta-blockers bad?

Beta-blockers can cause lung muscle spasms that make it difficult to breathe. This is more common in people who have lung conditions. High blood sugar (hyperglycemia). Beta-blockers can trigger high blood sugar in people with diabetes.

Can you still exercise on beta blockers?

People who take beta blockers can still exercise regularly and see the cardiovascular benefits of working out. Those who aim for a target heart rate should keep in mind that their new target heart rate may be different while on a beta blocker.

Is atenolol beta 1 selective?

Atenolol is a beta-1 selective (or cardioselective) beta blocker. This means that it mostly blocks beta-1 receptors, especially at normal doses. However, it can block beta-2 receptors in the lungs to some extent, especially at higher dosages.

What is a beta 1 receptor?

The beta-1 adrenergic receptor (β 1 adrenoceptor), also known as ADRB1, is a beta-adrenergic receptor, and also denotes the human gene encoding it. It is a G-protein coupled receptor associated with the Gs heterotrimeric G-protein and is expressed predominantly in cardiac tissue.

What is beta 1 blocker?

Beta-1 selective blockers for treatment of high blood pressure. 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).

What is a selective beta blocker?

Selective Beta-Blockers. Selective beta-blockers “select” the beta receptors located in the heart tissue, known as your beta1 receptors. This type of beta-blocker decreases activity around the heart and can help reduce your heart rate and your systolic pressure, the pressure your blood vessels experience when your heart beats.
