The metered dose inhaler (MDI) consists of a pressurized canister of medication in a plastic case with a mouthpiece. Pressing the MDI releases a mist of medication. When inhaled correctly, the medication has a better chance to reach the small airways. This increases the medication's effectiveness. Its portable size, efficiency and convenience make the MDI a desirable method for inhalation treatment.
