Lab study evaluating medication delivery MDI alone vs new portable spacer  

RESULT: Portable spacer provides optimum delivery without need for inhalation coordination.

Today Trudell Medical International announces it is extending its global footprint with its expansion into the Australian market with the establishment of Trudell Medical Australia Propriety Limited (Trudell Medical Australia).

Medications to manage care of bronchiectasis and NTM patients are often delivered via a nebulizer. This study compares a number of different OPEP/Nebulizer combinations using salbutamol as the modelled medication.

More consistent dose delivery was achieved with the breath actuated technology rather than breath enhanced. Delivering medication only when the patient inhales would result in more stable therapy if I:E ratio was to change with disease< progression or if the patient took breaks to talk during treatment.

Summary:

Presented at DDL 2017 in Edinburgh

• Valved holding chambers are widely prescribed to assist patients receiving inhaled medications by avoiding losses caused by imperfect coordination of inhalation and actuation and also to reduce oropharyngeal deposition.
• Regardless of whether using a solution based formulation (like Qvar) or a suspension formulation (Flovent), the use of a valved holding chamber reduced the amount of medication deposited in the mouth (oropharynx) and increased the potential for lung delivery
• This study can be used to help demonstrate the value of using a valved holding chamber for both solution and suspension formulated metered dose inhalers and for all patient populations, including adults

Short-acting beta2 agonist (SABA) monotherapy is typically required to provide as needed short term relief of bronchoconstriction. The salbutamol EasyHaler† DPI has recently become available in the UK as an alternative to delivery by pressurized metered-dose inhaler. Our study evaluated delivery from this DPI at different inhalation flow rates.

This study was presented at CHEST Conference 2023. 

As current MDIs contain hydrofluorocarbon propellants, it would be beneficial to find ways to reduce carbon emissions without compromising patient safety.

This lab study investigated a way to optimize the modelled lung dose per actuation while at the same time minimizing the carbon emissions from the MDI

Conclusion

• The delivery of medication from the AEROECLIPSE* II BAN* to the lungs was not affected by the incorporation of the Aerobika* OPEP device. Aerosol deposition within the lung was unaltered by the addition of the OPEP device as evidenced by the near identical percentage of the dose being deposited in both the peripheral and central airways.
• BAN+OPEP therapy could offer the clinician the opportunity for combined treatment thereby reducing the time needed for the patient to take both nebulizer and OPEP treatments separately.

Depending on the pMDI/spacer system chosen the delivery of medication can vary significantly and as a result will have implications on the potential carbon footprint.

In this case, the use of the AeroChamber Plus* Flow-Vu* VHC could potentially reduce the carbon footprint by three fold compared to the alternative spacers.

By maximizing the amount of each puff reaching the lungs the patient is likely to be able to get relief sooner and reduce the amount of puffs needed.

Conclusions:

• 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

Does Spacer/Adapter Device Choice Affect Delivery of a Pressurized Metered Dose Inhaler (pMDI) through a Humidified Circuit to a Simulated Patient on Mecha

RDD 2020 - E-Poster Presentation

COPD is a chronic and progressive disease that requires regular self-administration of inhaled medications. However, as the disease progresses, reduced respiratory muscle strength may prevent patients from generating sufficient inspiratory effort to effectively use dry-powder inhalers (DPIs) [1, 2]. In contrast, patients can inhale slowly or breathe tidally from a pMDI with VHC without the need to coordinate with inhaler actuation [3].

The FRI deposition profiles highlighted significant differences between the VHCs on test, with intrathoracic delivery for the AeroChamber Plus* Flow-Vu* VHC system being almost double that of the other two VHC systems and being similar to the MDI alone with perfect coordination
