An inhaler is a medical device used to deliver medication directly into the lungs for the treatment of respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It is a compact, portable device that is easy to use and can provide quick relief from symptoms. The inhaler typically consists of a mouthpiece, a medication canister, and a mechanism for releasing the medication in a fine mist that can be inhaled deeply into the lungs. Some inhalers also include a dose counter to keep track of the number of doses remaining. Inhalers are a convenient and effective way to manage respiratory conditions and improve quality of life.
