WebThe Easson-Stedman hypothesis explains how ana-logues of (R)-epinephrine can bind selectively to β2-adrenoceptors and why eutomers of sympathomimetics [eg, (R)-albuterol] will be far more potent in promoting receptor activation than distomers [eg, (S)-albuterol]. The consequences of activation of β2-adrenoceptors have been documented extensively.
