bronchodilator

 [brong″ko-di-la´tor]
1. expanding the lumina of the bronchi.
2. an agent that does this. Epinephrine is one of the most powerful bronchodilators and can be administered by injection or by aerosol. Isoproterenol (Isuprel) affects the bronchi by relieving bronchospasm through its action on smooth muscle. It is one of the most widely used aerosol bronchodilators. Other drugs used to enlarge the lumen of the bronchi and thereby facilitate breathing and removal of secretions include isoetharine, atropine, and aminophylline.
