The  synthetic catecholamine isoproterenol is also used in the treatment  of these diseases.    Epinephrine is a powerful bronchodilator, meaning it relaxes  bronchial muscle. It also constricts pulmonary vessels (in the  lung), and inhibits the release of histamines triggered by allergic  reactions.
