===Meter-dosed inhaler (MDI)===
The most common type of inhaler is the pressurized [[metered-dose inhaler]] (MDI) which is made up of 3 standard components- a metal canister, plastic actuator, and a metering valve. The medication is typically stored in solution in a pressurized canister that contains a propellant or suspension. The MDI canister is attached to a plastic, hand-operated actuator. On activation, the metered-dose inhaler releases a fixed dose of medication in [[Aerosol spray|aerosol]] form through the actuator and into a patient's lungs.<ref>{{cite book|url=https://archive.org/details/pharmaceuticalin134anth|title=Pharmaceutical Inhalation Aerosol Technology|publisher=Marcel Dekker|year=2004|editor=Hickey, A.J.|edition=2nd|location=NY|isbn=9780824742539|url-access=registration}}</ref>  These devices require significant coordination as a person must discharge the medication at or near the same time that they inhale in order for the medication to be effective.<ref name=":5">{{cite journal | vauthors = Navaie M, Dembek C, Cho-Reyes S, Yeh K, Celli BR | title = Device use errors with soft mist inhalers: A global systematic literature review and meta-analysis | journal = Chronic Respiratory Disease | volume = 17 | pages = 1479973119901234 | date = January 2020 | pmid = 31984767 | pmc = 6985977 | doi = 10.1177/1479973119901234 }}</ref>
