COPD inhalers are vital to helping people with chronic obstructive pulmonary disease (COPD) live a normal life, alleviating not just their symptoms but also their overall distress. This is why they are so commonly used, and why there are now so many different models are available. Most of the time, inhalers contain corticosteroids or bronchodilators. Sometimes, they contain a combination of both. The most common brands are Advair, Combivent, Pulmicort, and Symbicort.
