is nebivolol a selective beta blocker?
240217
Nebivolol is a novel, highly selective beta-blocker with nonadrenergic vasodilating properties. It has been approved for the treatment of essential hypertension and congestive heart failure in Europe and is currently under review for the treatment of hypertension in the US.

Asthmatic subjects are the special “group of risk” with relative contraindications for this therapy. The novel highly selective β blocker nebivolol which additionally posses vasodilatatory effect through nitric oxide release is potentially safe in asthma.

Labetalol is a dual alpha (α1) and beta (β1/β2) adrenergic receptor blocker and competes with other Catecholamines for binding to these sites. Its action on these receptors are potent and reversible. Labetalol is highly selective for postsynaptic alpha1- adrenergic, and non-selective for beta-adrenergic receptors.

Do not stop taking Bystolic (nebivolol) all of a sudden. If you do, chest pain that is worse and in some cases heart attack may occur. The risk may be greater if you have certain types of heart disease. To avoid side effects, you will want to slowly stop Bystolic (nebivolol) as ordered by your doctor.

Beta-blockers are prescribed for patients with systolic heart failure and improve survival, even in people with severe symptoms. There are several types of beta-blockers, but only three are approved by the FDA to treat heart failure: Bisoprolol (Zebeta) Carvedilol (Coreg)

Newer beta blockers, such as carvedilol (Coreg), don't usually cause weight gain as a side effect.

Atenolol and bisoprolol are both beta-blockers and are used to help treat high blood pressure, angina and heart failure. Atenolol is a much older drug and is now less often prescribed for cardiac patients. Bisoprolol was developed to be more cardio-specific than atenolol.

When taken in very high doses, beta blockers can worsen heart failure, slow the heart rate too much, and produce wheezing and a worsening of lung disease. High doses may also cause lightheadedness from a drop in blood pressure, which puts people at risk for falls and injury.

2 Pindolol possesses partial agonist activity (intrinsic sympathomimetic activity, ISA). This means that apart from blocking beta-adrenoceptors it produces some stimulation. Pindolol therefore only slightly influences normal sympathetic drive at rest but effectively reduces the effects of elevated sympathetic activity.

Beta Blockers fit into the 'one pill can kill” category, and a small child could have significant cardiac effects from a pill or two.

Newer beta blockers, such as carvedilol (Coreg) and nebivolol (Bystolic), are less likely to affect your cholesterol levels. If you're worried about increasing triglyceride levels, talk to your doctor about making changes to your diet and exercise routine.

Conclusions. Cardioselective beta-blockers prescribed to people with asthma and CVD were not associated with a significantly increased risk of moderate or severe asthma exacerbations and potentially could be used more widely when strongly indicated.

Coreg (carvedilol) and Lopressor (metoprolol tartrate) are beta-adrenergic blocking agents (beta-blockers) used to treat heart failure, hypertension, and heart attacks.

Nebivolol is used alone or in combination with other medications to treat high blood pressure. Nebivolol is in a class of medications called beta blockers. It works by relaxing blood vessels and slowing heart rate to improve blood flow and decrease blood pressure.

Non-cardioselective beta blockers, like propranolol or nadolol, helps minimize arrhythmias, blood pressure, heart rate, and the workload on the heart. ... Cardioselective beta blockers, like atenolol and esmolol, avoid the latter problem by targeting and affecting just the beta-1 (heart) receptors.

Does Bystolic (nebivolol) work immediately? No, it can take up to about 4 hours for Bystolic (nebivolol) to start working, and several weeks before you get the full benefits. Keep taking this medication even if you feel well as most people with high blood pressure do not feel symptoms.
