What is the primary benefit of using a 'spacer' or holding chamber with a metered-dose inhaler (MDI) of Albuterol?
Show answer and explanation
Correct answer: It reduces oropharyngeal deposition and improves lung delivery
Spacers allow the large, high-velocity particles to settle in the chamber, while smaller particles stay suspended. This ensures more of the drug reaches the lower airways and less is swallowed, reducing systemic side effects.
