The US Food and Drug Administration confirmed that it is going ahead with the ban on asthma inhalers that use chlorofluorocarbons (CFCs) since it harms the environment.

Primatene Mist, manufactured by Armstrong Pharmaceuticals, is the only such inhaler marketed in the United States and is thought to be used by more than a million asthma patients in the country.
The FDA added that all inhalers that contain the drug epinephrine will be banned starting from next year. Two other prescription inhalers that make use of the drug; Boehringer Ingelheim's Combivent Inhalation Aerosol and Graceway Pharmaceuticals' Maxair Autohaler., will also be phased out by the end of 2013.
