Nebivolol (also known as R-65824) potently and selectively inhibits β1-adrenoceptor with IC50 of 0.8 NM. Nebivolol shows high affinity and selectivity for beta 1-adrenergic receptor sites in a rabbit lung membrane preparation (Ki value = 0.9 nM and beta 2/beta 1 ratio = 50). Nebivolol displays β1-adrenoceptor selectivity with the Ki(β2)/Ki(β1) value of 40.7 judged by competition experiments to 3H-CGP 12.1777 in the presence of CGP 207.12 A (300 nM, Kiβ2) or ICI 118.551 (50 nM, Kiβ1).
