An aerosol metered-dose inhaler (MDI)

An inhaler or puffer is a medical device used for delivering medication into the body via the lungs. It is mainly used in the treatment of asthma and Chronic Obstructive Pulmonary Disease (COPD).


Medication is most commonly stored in solution in a pressurized canister. The canister is attached to a plastic, hand-operated actuator. For example, the metered-dose inhaler (MDI) on activation releases a fixed dose of medication in aerosol form. The correct procedure for using a MDI is to first fully exhale, place the mouth-piece end of the pump into the mouth, and having just started to inhale, depress the canister to release the medicine. The aerosolized medication is drawn into the lungs by continuing to inhale deeply before holding the breath for 10 seconds to allow absorption into the bronchial walls.

Alternatively a complementary spacer devise may be used, of which is an enclosed plastic chamber that mixes the medication with air in a simple tube, making it easier for patients to receive a full dose of the drug.
