What is a Meter Dose Inhaler (MDI) primarily used for?

A Meter Dose Inhaler (MDI) is primarily used for pushing premeasured sprays of medication directly into the lungs. This device is designed to deliver a specific dose of medication with each actuation, ensuring that patients receive an accurate amount of their prescribed medication every time they use it.

MDIs are commonly used for respiratory conditions, such as asthma or chronic obstructive pulmonary disease (COPD), allowing for quick and effective relief from bronchospasms or other symptoms. The premeasured aspect of the MDI ensures that regardless of user technique, a consistent dose is administered each time, which is critical for effective management of these conditions.

Other options do not accurately reflect the function of an MDI. For example, MDIs do not provide continuous nebulizer treatment, which typically involves a different device that delivers medication continuously over a longer period. Additionally, while MDIs are used for medication delivery, they do not automatically deliver medication daily or store liquid medication. Instead, MDIs are compact, portable devices designed for on-demand administration of inhaled medication. Thus, the focus on premeasured doses is central to the MDI’s design and function.
