Selective beta blockers, for example, metoprolol (Lopressor, Toprol XL) primarily block β1 receptors and, therefore, mostly affect the heart and do not affect air passages. Some beta blockers, for example, pindolol (Visken) have intrinsic sympathomimetic activity (ISA), which means they mimic...
Beta blockers Last updated: November 15, 2024 Summary Beta blockers are a group of drugs that inhibit the sympathetic activation of β-adrenergic receptors. Cardioselective blockers (e.g., atenolol, bisoprolol) primarily block β1 receptors in the heart, causing decreased heart rate, cardiac con...

first-generation or nonselective beta-blockers can cause an asthma attack ortrouble breathingif you smoke, have asthma, or other lung conditions. If you have mild asthma or lung disease, your doctor may try a selective beta-blocker, but they will usually avoid using them in people with moder...

It is therefore expected that non-selective beta blockers have anantihypertensiveeffect. The antihypertensive mechanism appears to involve: reduction in cardiac output (due to negative chronotropic and inotropic effects), reduction inreninrelease from the kidneys, and a central nervous system effect to ...
Use of beta-blockers linked to acute kidney injury, mortality in decompensated cirrhosis Use of nonselective beta-blockers was associated with stage 2 acute kidney injury and all-cause mortality among patients with decompensated cirrhosis waitlisted for liver transplantation, data showed. ...
Cardioselective ß blockers are not associated with increased respiratory symptoms or inhaler use in patients with COPD or reactive airway disease and are associated with an augmented FEV1 response after ß-2 agonists compared with placebo. Conversely, ß-2-agonist use is associated with the de...
