Environmental pollution not only makes asthma worse we are, but could make asthma inhalers were less effective.
It is the conclusion of an investigation led by Dr. Fernando Holguin, University of Pittsburgh, in which we studied 85 asthmatic children in Mexico City, famous for its high levels of pollution.
Contaminants that most affect the effectiveness of inhalers and the ozone would be nitrogen dioxide.
An increase of ten parts for my million of nitrogen dioxide, impairing the effectiveness of inhalers by 15%.
However, this decrease in effectiveness would not occur because drugs stop working, but because asthmatics do not respond as they would in the absence of contamination.
