Unlabelled: The correct use of inhaler devices is important for the efficacy of the treatment of childhood asthma. Few studies have compared the use of inhaler devices in real life, in particular in children.
Aim: To determine whether such devices were correctly used in asthmatic children within a primary care setting.
Population And Methods: Three hundred and sixty-four children aged 5 to 18 years (mean+/-SD: 14.1+/-3.3) treated for at least 1 month by an inhaler device were included. During a routine visit to the doctor, the primary care physician assessed the childrens' handling of their current device, using a checklist established for each device from the package leaflet.
Results: At least half of the patients made at least 1 error, regardless of the inhaler used. The best result was obtained with the Diskus (46% error-rate) and the worst with the pressurized metered-dose inhaler (pMDI) (78% error-rate). The rank order of increasing critical-error rate (at least 1 error) was as follows: Diskus (6%)
Conclusion: Irrespective of the type of device used, many errors are committed in real-life use. Overall, the Diskus, the Autohaler and the Aerolizer devices are more correctly used than the Turbuhaler or the pMDIs. However, it would be relatively easy to rectify all the errors identified by this study by simple educative measures.

Nitric oxide (NO) is an essential molecule in biomedicine, recognized for its antibacterial properties, neuronal modulation, and use in inhalation therapies. The effectiveness of NO-based treatments relies on precise control of NO concentrations tailored to specific therapeutic needs. Electrochemical generation of NO (E-NOgen) via nitrite (NO ) reduction offers a scalable and efficient route for controlled NO production, while also addressing environmental concerns by reducing NO pollution and maintaining nitrogen cycle balance.

/: Inhaler devices have been developed for the effective delivery of inhaled medications used in the treatment of pulmonary diseases. However, differing operating procedures across the devices can lead to user errors and reduce treatment efficacy, especially when patients use multiple devices simultaneously. To address this, we developed a novel dry powder inhaler (DPI), combining fluticasone propionate (FP), salmeterol xinafoate (SX), and tiotropium bromide (TB) into a single device designed for bioequivalent delivery compared to existing commercial products in an animal model.

Dry powder inhalers (DPI's) are becoming increasingly popular due to growing interest in pulmonary drug delivery and their performance is the net result of a series of processes carried out during the formulation development and manufacturing process such as excipient selection, blending, milling, filling, and spray drying. To reach the small airways of the deep lung, the active pharmaceutical ingredients (API) particles need to have an aerodynamic diameter of 1-5 μm to avoid impaction and particle sedimentation in the upper respiratory tract, and due to this small particle size, the powder becomes highly cohesive resulting in poor flow. Therefore, API is usually blended with a coarse carrier to improve flowability, and due to its large size, it is more fluidizable than the micronized drug.

: Metered-dose inhalers (MDIs) and dry powder inhalers (DPIs) are common inhaled corticosteroid (ICS) inhaler devices. The difference in formulation and administration technique of these devices may influence oral cavity microbiota composition. We aimed to compare the saliva microbiome in children with moderate-to-severe asthma using ICS via MDIs versus DPIs.

The work aims to develop mucoadhesive and thermo-responsive in situ gelling systems, using hydrophobically-modified hydroxypropyl-methyl cellulose (Sangelose, SG) and beta-cyclodextrin (β-CD) derivatives, for preventing viral respiratory infections. Eight SG/CD systems with varying CD concentrations were evaluated for rheological properties, mucoadhesiveness, spreadability and sprayability via nasal devices; cytotoxicity was in vitro investigated on reconstituted nasal epithelia. Additionally, droplet size distribution and spray deposition were assessed for the most promising systems.
