What is an inhaler? An inhaler is a small, handheld device that delivers medication directly to your lungs. Inhalers can be dry powder, metered-dose or soft mist. The most common types use medicine that helps open your airways or reduce inflammation in your lungs.
Inhaler ... An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing.
Inhalers deliver medication directly to the lungs. These medications typically work to either reduce inflammation in the airways or to dilate the airways. Medications that dilate the airways are meant to enlarge their diameter to increase oxygen flow. These are called bronchodilators.
