Facemasks are commonly used by certain patients requiring assistance for aerosol medication delivery. Adapters are used as connectors between facemasks and inhalers. The valved holding chamber (VHC) is commonly prescribed with pressurized metered dose inhalers (pMDIs) to improve medication delivery. Recently, the VHC has been used with the Respimat Soft Mist Inhaler (SMI), which is a propellant-free inhaler. The ODAPT soft mist adapter was previously designed to serve as a connector for facemasks used with the Respimat SMI.

The Respimat Soft Mist Inhaler (SMI) is a propellant-free inhaler that generates a fine aerosol mist suitable for inhalation. For patients requiring facemasks for medication delivery, the presence of the facemask influences the lung deposition. The purpose of this study was to assess, in vitro, the effect of the attachment of add-ons (ODAPT soft mist adapter with facemask) to the Respimat SMI on the medication delivery under different conditions and evaluate the efficacy of the ODAPT with facemask.

L’aérosol est couramment utilisé pour administrer des médicaments thérapeutiques aux patients souffrant d’asthme et de maladies pulmonaires obstructives chroniques (MPOC). Cette étude in vitro a pour objectif de définir les effets de l’utilisation du masque facial EcoMask et de l’adaptateur ODAPT avec l’inhalateur Soft-Mist Spiriva Respimat (SMI) dans différents contextes.

Aerosol is commonly used to deliver therapeutic drugs to patient suffering from asthma and chronic obstructive pulmonary disease (COPD). The purpose of this in vitro study is to characterize the effect of using the EcoMask facemask and the ODAPT adapter with the Spiriva Respimat Soft Mist Inhaler (SMI) in different environments.
