Cardioselective beta blockers have a clinical advantage in that they are 20 times more potent at blocking beta-1 receptors than beta-2 receptors. They are therefore less likely to cause bronchoconstriction compared with non-selective beta-blockers; however, the danger of bronchoconstriction cannot be totally ignored, as they are not totally selective.
