The use of metered-dose inhalers (MDIs) for the treatment of diseases such as asthma has become popular since their introduction in the late 1950s. MDIs come in the form of nasal or oral inhalers and are much appreciated by patients who depend on them for their treatment. MDIs are designed to deliver precise/accurate and reproducible doses of the drug to the lungs or nose. This is crucial as patients rely on their inhaler to deliver the required medication at often crucial times when physical strength may be very low.
