Why might a patient prefer a dry powder device like Ellipta over an Advair MDI requiring a spacer?

Answer

To ensure medication reaches lower airways without forgetting/disliking the spacer

The choice between delivery methods, such as Metered Dose Inhalers (MDIs) which often require a spacer for optimal delivery, versus newer breath-actuated dry powder inhaler (DPI) systems like the Ellipta or Turbuhaler, significantly impacts patient adherence. A patient might express a preference for a DPI if they frequently forget to bring or dislike using a spacer accessory. DPIs allow the patient to inhale the medication directly upon activation by breath alone. This practical consideration ensures that the drug is more reliably deposited deep within the lower airways, regardless of the specific chemical composition of the preventer drug contained within the device.
