Bronchodilation

Bronchodilation is the expansion of the bronchial air passages in the respiratory tract. A bronchodilator is a substance that dilates the bronchial tubes, resulting in decreased resistance in the respiratory airway and increased airflow to the lungs.

Additionally some psychostimulant drugs that have an amphetamine-like mode of action, such as amphetamine, methamphetamine, and cocaine, have bronchodilating effects and were used often for asthma due to the lack of effective β2-agonists for use as bronchodilator, but are now rarely, if ever, used medically for their bronchodilation effect.
