Carvedilol, sold under the brand name Coreg among others, is a medication used to treat high blood pressure, congestive heart failure (CHF), and left ventricular dysfunction in people who are otherwise stable. For high blood pressure, it is generally a second-line treatment.[1] See also Carvedilol.
Carvedilol is both a non-selective β-adrenergic receptor antagonist (β1, β2) and an α-adrenergic receptor antagonist (α1). See also Adrenergic receptor. The S(–) enantiomer accounts for the beta-blocking activity whereas the S(–) and R(+) enantiomers have alpha-blocking activity.[2] The affinity (Ki) of carvedilol for the β-adrenergic receptors is 0.32 nM for the human β1-adrenergic receptor and 0.13 to 0.40 nM for the β2-adrenergic receptor.[3]
