title: Comparison of pharmacological and binding assays for ten beta-adrenoceptor blocking agents and two beta-adrenoceptor agonists.
abstract: 1 The inhibition constants evaluated by binding assays for ten beta-adrenoceptor blocking agents and two beta-adrenoceptor agonists, were compared with the pA2 and pD2 values determined in vitro and in vivo. 2 There was only a limited correlation between beta 1 or beta 2 selectivities observed with the different methods. 3 Selectivity is generally less pronounced in binding assays than for in vivo and in vitro experiments.
