Albuterol is widely used for the relief of asthma symptoms and is the primary rescue medication for asthma sufferers.More than 90 percent of the albuterol inhalers sold in the United States last year contained Chlorofluorocarbon, or CFC, propellants, which are believed to deplete the earth's ozone layer, Ivax said.
Instead, the Ivax inhaler uses a Hydrofluoroalkane, or HFA, propellant.
