Asthma treated effectively by dry inhaler powder
Asthma inhalers are often mistaken to be addictive and some if them are said to be ineffective however, switching from a metered dose inhaler to a dry powder version for maintenance therapy more than halves the carbon footprint of people with asthma, and without any worsening of their condition, finds a pharma industry sponsored study published online in the journal Thorax.
The use of chlorofluorocarbons (CFCs) in aerosol propellants was banned under the 1987 Montreal Protocol agreement because of their impact on global warming. This substitution would be an acceptable and worthwhile 'green' option for most patients who can safely manage their condition at home, and should be widely encouraged, conclude the researchers.
