Acts on both Alpha and Beta-adrenergic receptors: α1-adrenoceptor vasoconstriction, so that blood is shunted to the body's core, and the β1-adrenoceptor response which is increased cardiac rate and output (the speed and pronouncement of heart beats).α1-adrenoceptorvasoconstrictionβ1-adrenoceptor Also acts a bronchodilater
