WASHINGTON (AP) -- The government is asking asthma patients and doctors for help in deciding if it is time to gradually pull off the market certain asthma inhalers that pollute the environment. Older asthma inhalers use CFCs, the chlorofluorocarbons that deplete the ozone layer. An international treaty requires that they be phased out once suitable alternatives are available. Two CFC-free inhalers containing the popular asthma medicine albuterol, a bronchodilator, are on the market.
The Food and Drug Administration on Wednesday proposed gradually phasing out the four other albuterol inhalers sold that use CFCs. Because albuterol can be lifesaving for patients with asthma and certain other lung diseases, the FDA wants to hear from the public if those two alternatives are adequate before it makes a final decision next summer on how soon CFC-containing albuterol could be phased out.
Among the questions are whether patients think the CFC-free versions perform as well, said the FDA's Dr. Robert Meyer. The agency has tentatively concluded that they do. The two CFC-free inhalers, Proventil HFA and Ventolin HFA, make up only about 7 percent of the albuterol market, and production would have to increase, Meyer noted. They cost at least $10 more than generic albuterol inhalers and generic CFC-free versions may not be possible until 2010 or later, he said.
The FDA planned to begin soliciting opinion Thursday at a meeting of its independent scientific advisers. The public has 60 days to submit comments as well.
