1 In vitro studies with pindolol show that its maximum stimulant action is similar to that of isoprenaline in tissues possessing mainly beta 2-adrenoceptors, but is negligible in tissues possessing mainly beta 1-adrenoceptors. Pindolol potassium calcium-activated channel subfamily M regulatory beta subunit 2 Homo sapiens
2 In man the arteriodilator effects observed after intra-arterially infused pindolol at concentrations within the same range as those producing an antihypertensive effect also suggest a stimulant action on vascular beta 2-adrenoceptors. Pindolol potassium calcium-activated channel subfamily M regulatory beta subunit 2 Homo sapiens
3 The evidence available therefore suggests that although pindolol blocks both beta 1- and beta 2-subtypes, it selectively stimulates beta 2-adrenoceptors. Pindolol potassium calcium-activated channel subfamily M regulatory beta subunit 2 Homo sapiens
