The widely differing inspiratory flow profiles from Turbuhaler† DPI contributed to greater variability in delivered dose to the carina.
MDI delivery via the AeroChamber Plus* Flow-Vu* VHC resulted in significantly increased mass to the carinal region irrespective of inhalation maneuver as well as reduced oropharyngeal deposited mass which in vivo is likely to result in reduced throat irritation or thrush in the mouth and throat.
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.
Evaluations of inhaler use have demonstrated that mishandling of MDIs is commonplace.
One of the most common errors is the failure to coordinate inhalation with actuation of the inhaler
One of the reasons why VHCs are often prescribed, is to reduce the severity of this error
This Functional Respiratory Imaging (FRI) based study assessed the likely severity of a short inhalation delay (from actuation) with an MDI alone and how it contrasted to the use with a VHC
Bronchiectasis is a chronic, progressive lung condition affecting infants, children and adults. While the global prevalence of bronchiectasis is not accurately known,1 there is a growing awareness of the disease.2
Chronic Obstructive Pulmonary Disease (COPD) affects around 251 million people globally.1 It is a term that covers two types of chronic (long-term) diseases where the airways in the lungs become “obstructed” or partly blocked.
Asthma is a chronic respiratory disease, characterized by narrowing of the airways and excess mucus production. People with asthma typically suffer from chest tightness/pain, shortness of breath, and episodes of coughing and wheezing.
Join Dr. Douglas Mack and Dr. Mariam Hanna as they discuss the importance of asthma control in today’s world, as well as the shift to virtual appointments including tools and tips to optimize virtual asthma assessments. Please see a recording of the session below.
The webinar will cover:
Asthma measures for Back to School amid COVID-19
The reality of asthma in Canada – misperception about asthma
When to conduct virtual vs face-to-face appointments
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
Management of your respiratory condition such as asthma or COPD is more important than ever. As such, we would like to invite you to join Dr. Douglas Mack and Dr. Mariam Hanna as they discuss:
How to best manage your and/or your child’s asthma
