Inhaled drugs for asthma are available in the US mainly in pressurized metered-dose inhalers (MDIs), which require a propellant, and dry powder inhalers, which do not. The chlorofluorocarbon (CFC) propellants in MDIs are being replaced by hydrofluoroalkane (HFA) propellants for environmental reasons: CFCs contribute to the depletion of the ozone layer. December 31, 2008 will be the last day that albuterol MDIs using CFC propellants can be sold in the US. The FDA is expected to announce a termination date for other CFC-containing products in the near future.Three HFA albuterol inhalers and one...
