WASHINGTON, Sept 20 (Reuters) - U.S. health officials on Thursday proposed phasing out the use of chlorofluorocarbons (CFCs) in metered-dose asthma inhalers that contain the drug epinephrine.The Food and Drug Administration said it had tentatively concluded that there were no substantial technical barriers to making epinephrine inhalers that did not release CFCs, which are used as propellants but deplete the Earth’s ozone layer.
