名詞
Inhalers can deliver medicines to the airways that help prevent asthma attacks, relieve symptoms during an asthma attack, or do both. The Metered-dose inhaler (MDI) is the most commonly used type of inhaler. It has a boot-shaped mouthpiece into which a pressurized, medicine-containing canister is inserted. This design has been in use since 1956. You deliver a measured dose of the medicine to your lungs by inserting the mouthpiece into your mouth and pushing down on the canister while inhaling.
