we investigated the effects of beta 2- ( procaterol 2 x 50 micrograms/day for 9 days ) and beta 1- ( xamoterol 2 x 200 mg/day for 14 days ) adrenoceptor agonists on lymphocyte beta 2-adrenoceptor density and beta 1- and beta 2-adrenoceptor in vivo function ( assessed as isoprenaline-infusion-evoked hemodynamic effects and exercise-induced tachycardia ) in healthy volunteers .
