Salbutamol is used to open airways in such conditions as asthma, however now it is available in a chlorofluorocarbon (CFC) free metered inhaler. These inhalers use hydrofluoroalkanes or HFA's.
These inhalers do not contain the CFC's which cause ozone damage. The inhaler has been redesigned - valves and surfactants have been changed.
With HFA's the spray is "softer". There is no cold, freon-like effect on the back of the throat.
People must realize, before they use these inhalers that the lack of a feeling of coldness at the back of the throat does NOT mean that the inhaler is not working.
These inhalers provide a more consistent dose in that there are fewer problems due to temperature changes or storage position.
