Bronchodilators may be [[endogenous|originating naturally within the body]], or they may be [[medication]]s administered for the treatment of breathing difficulties, usually in the form of [[inhaler]]s. They are most useful in [[obstructive lung disease]]s, of which [[asthma]] and [[chronic obstructive pulmonary disease]] are the most common conditions.
