Which drugs are beta-1 blockers?
The cardio-selective beta-1-blockers include atenolol, betaxolol, bisoprolol, esmolol, acebutolol, metoprolol, and nebivolol.
What is the most beta-1 selective beta-blocker?
Non-selective, cardioselective and vasodilating beta-blockers
| Beta-blocker | Selectivity | Vasodilation |
|---|---|---|
| Atenolol | β1 selective | No |
| Bisoprolol | β1 selective++ | No |
| Carvedilol | Non-selective | Yes |
| Celiprolol | Non-selective | Mild |
What is the action of beta-1 blockers?
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 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.
Is metoprolol b1 selective?
Metoprolol, a beta-1 selective blocker, can be used safely in coronary artery disease patients with chronic obstructive pulmonary disease. Heart Vessels. 2003 Sep;18(4):188-92.
When are beta blockers used?
They are used to treat conditions including angina, heart failure and some heart rhythm disorders, and after a heart attack. They are also sometimes prescribed for glaucoma, anxiety and migraines. Common beta blockers include: atenolol (brand names include Tenormin)
What is a beta-1 beta blocker?
Beta blockers, also known as beta-adrenergic blocking agents, are a class of drugs that works by blocking the neurotransmitters norepinephrine and epinephrine from binding to receptors. There are three known types of beta receptors, known as beta1 (β1), beta2 (β2) and beta3 (β3).
What is the strongest beta blocker?
Which beta blocker is most effective?
- Atenolol (Tenormin)
- Betaxolol (Betoptic eye drops, Kerlone tablets)
- Bisoprolol (Zebeta)
- Esmolol (Brevibloc injection)
- Metoprolol tartrate (Lopressor)
- Metoprolol succinate (Toprol XL)

Is metoprolol a beta-1 or 2 blocker?
Metoprolol, a beta-1 selective blocker, can be used safely in coronary artery disease patients with chronic obstructive pulmonary disease. Heart Vessels.
Is metoprolol a B1 or B2?
Metoprolol, sold under the brand name Lopressor, among others, is a selective β1 receptor blocker medication. It is used to treat high blood pressure, chest pain due to poor blood flow to the heart, and a number of conditions involving an abnormally fast heart rate.
Is propranolol a beta-1 or 2?
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.
