The DPI results suggest that inhalation breathing profiles can have an appreciable impact upon aerosol delivery, with one participant having much less predicted medication as fine particles
In contrast, although the inhalation profiles across all participants were also divergent when asked to inhale from the pMDI + VHC, either tidal breathing or by a slow, deep inhalation, all volunteers would have received a relatively consistent amount of medication.
It also appears that the pMDI + VHC platform delivers a larger FPM<5.0 µm for both APIs and a consequently smaller coarse particle mass. However, it is recognized that more investigation is warranted with a larger number of volunteers and with other passive DPIs having different resistances
The most efficient and effective delivery method remains that recommended in the device IFU (one actuation inhaled at a time, as well inhalation as soon as possible after actuation)
However, this laboratory-based study has indicated that a modified common-canister protocol with an anti-static VHC as the aerosol transfer vehicle has the potential to be a viable ‘off-label’ proposition in hospital situations where there is an urgent need to conserve pMDI medication as well as avoid cross-contamination from pathogenic viruses or bacteria
While it’s one of the most anticipated seasons of the year, summer can also be the most difficult season for Canadians living with COPD (chronic obstructive pulmonary disease). We want to help you make the most of it! Here’s what you need to know about summer, and how you can enjoy yours this year.
Cystic fibrosis (CF) is a progressive, genetic condition affecting more than 100,000 people worldwide.1 There are over 4,300 people living with CF in Canada.2
Asthma impacts different people in different ways. Most people are able to control their asthma with regular use of their controller medication and using their reliever medication when necessary. However, for many it can be difficult to recognize when their asthma is not controlled. When asthma is well-controlled, you will experience little to no asthma symptoms.
