A bronchodilator is a substance that dilates the bronchial tubes, resulting in decreased resistance in the respiratory airway and increased airflow to the lungs.
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. Caffeine is also an effective bronchodilator. In clinical tests on adults with athsma, at fairly low doses (5mg/kg of body weight), caffeine has been shown to provide a small improvement in lung function, such that it needs to be controlled for in diagnostic tests.[1]
