- The FRI deposition profiles highlight that the MDI/ AeroChamber Plus* Flow Vu* VHC system delivered an appreciably greater percentage of drug to the lung region than either of the two DPIs.
- The influence of inhalation flow profile was less with the MDI/VHC system and differed between the two DPIs.
