WebJul 28, 2024 · Selective beta blockers — also known as cardioselective beta blockers — only block beta-1 (β1) receptors in the body. These receptors (chemical binding sites) affect your heart rate and how much blood your heart pumps out. Examples of cardioselective beta blockers include: Atenolol (Tenormin) Betaxolol (Betoptic eye drops, Kerlone tablets) WebCarvedilol and labetolol are nonselective beta and alpha blocking drugs. Carvedilol is used in the treatment of CHF as an adjunct to conventional treatments (ACE inhibitors and diuretics).
