HealthDay - Ozone-Depleting Inhalers Being Phased Out
Asthma inhalers that contain the drug albuterol to relax the airways also contain chemicals that harm the ozone layer. And these inhalers won’t be available after this year, so U.S. health officials are urging patients to switch to alternative inhalers now.
Chlorofluorocarbons, or CFCs, are widely used to propel inhaled drugs into the lungs. However, products containing CFCs are being phased out, because the chemicals damage the Earth’s protective ozone layer. CFC inhalers are being replaced by inhalers powered by HFAs, or hydrofluoroalkanes, which are ozone-friendly.
