ProAir is a brand name for albuterol inhalers used to treat asthma and COPD. The active drug in ProAir is albuterol, which works by relaxing muscles in the airways to improve breathing. ProAir comes in multiple forms like the ProAir HFA inhaler, ProAir Digihaler, and ProAir Respiclick. The ProAir HFA inhaler provides a measured dose of albuterol with each actuation. The Digihaler version monitors inhaler use and helps coach proper inhaler technique. The Respiclick inhaler is breath-actuated to deliver albuterol when the person inhales. ProAir inhalers provide 90 mcg or 100 mcg per actuation. ProAir and other albuterol inhalers provide fast relief for asthma attacks and COPD flare-ups by quickly opening the airways within 5-15 minutes. ProAir inhalers are prescribed for both maintenance and rescue use.
