An inhaler is a medical device used for delivering medicines into the lungs through the work of a person's breathing.

What an inhaler does?

Bronchodilators, or most commonly called inhalers, are medications that are breathed through the mouth and into the lungs to help relax muscles that tighten around your airways. The medicine helps open the airway and lets more air move in and out of your lungs and helps you breathe more easily.

What are the two types of inhalers?

Inhalers can be classified into two categories: Metered dose inhalers (MDIs) and Dry powder inhalers. Metered dose inhalers are usually used as asthma rescue inhalers or reliever medicines.
