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.
Caffeine is 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. [1] Some psychostimulant drugs that have an amphetamine-like mode of action (such as amphetamine, methamphetamine, and cocaine) also have bronchodilating effects.
