<s>[INST] What effects do airway opener medications have? [/INST] Airway openers work by opening up the narrowed airways. They do this by relaxing the muscles surrounding the airways. This makes it easier to get air in and out of the lungs. Most airway openers work quickly and can be used to treat an asthma attack. They are sometimes called relievers or rescue bronchodilators.
