Increased Levels of Outdoor Air Pollutants Are Associated With Reduced Bronchodilation in Children With Asthma.

The article presents a study which correlates the efficacy of short-acting β-agonists (SABAs) and the action of air pollutants which affects children with asthma. It notes that the study was conducted through examination of components in air pollutants including nitrogen dioxide (NO2), ozone (O3) and air particulates. It suggests that exposure to NO2 and O3 reduces the potency of SABAs in initiating bronchiodilation.
