This Month’s Focus: Devices
Penetration enhancers and mucoadhesives in liquid nasal spray formulations
Some commercially available liquid nasal spray formulations include excipients that can act as penetration enhancers or mucoadhesives. They may thereby provide the benefit of increasing contact/residence time in the nasal cavity or increasing absorption of drug molecules by enhancing permeability through nasal mucosal membranes. This review may assist readers in considering the utility of various penetration enhancers and mucoadhesives for use in research and development.
Propellant and formulation properties for next-generation pMDIs: Measurement, representation and prediction
In this article, the fundamental thermophysical properties that control the complex internal flow and aerosol formation process in a pMDI will be examined, from the perspective of their measurement, representation and prediction. Activity coefficient models that enable simultaneous description and prediction of important formulation thermophysical properties will also be presented. The performance of these models is demonstrated using existing data for HFA134a/ethanol mixtures, to show their potential application alongside experimental property data collection involving future propellants.
General Features
Cross-Industry Organizations: Respiratory Drug Delivery 2022: Bringing the respiratory world together in person and virtually
RDD 2022 will be held in person in Orlando, Florida, May 1-5, 2022. However, the best ways of interacting will allow delegates who are not yet ready, willing or able to travel to the US to participate. Further, if an in-person conference becomes impractical for any reason, the organizers are well equipped to revert to a virtual event.
Back Pages: Food allergies increase challenges for people facing food insecurity. Is food insecurity associated with asthma? Study results conflict
For millions in the US newly experiencing food insecurity due to the COVID-19 pandemic, those with food allergies are facing “a particular crisis” in that most charitable and government food programs offer limited options that are safely edible. The Food Equality Initiative and Porchlight Community Services are two organizations that support clients with food allergies. Multiple studies have been conducted to determine whether food insecurity is associated with asthma and, if so, to evaluate the extent of such a relationship. However, results are conflicting.
Previewing the DDL2021 Virtual Conference
Due to COVID-19, Drug Delivery to the Lungs 2021 (DDL2021) will be presented live online, December 8-10, replacing the in-person event originally planned for the same dates in Edinburgh, UK. Conference highlights will include scientific presentations, a sponsor exhibition, awards and the New Researcher Network Discussion Forum. Content will be presented in a single stream, enabling attendees to view all of the conference’s live content.

Inhalation Article Guidelines
Technical article requirements
The article should be technical and educational, but not promotional. It must be new, not previously published and must be at least 50% different from your previous articles or other articles you are simultaneously developing on the same subject.
All discussions of products or technologies must be in an unbiased, non-promotional, educational manner. If your article discusses products that have been commercialized or are in development, please be aware of the following: Inhalation takes a very limited approach in discussing products, usually listing only product name, delivered drug name and company name, unless a description is provided by the particular company that owns a product, such as in a case study article or product news release. In that way, each company can choose the information it wishes to discuss or disclose about its own products, rather than being discussed by an outside party with no ability to comment prior to publication. However, if an article is a case study, presentation of a novel technology or news article written by the owner company or its representative such as a scientist or consultant, we are happy to consider all information or data they wish to disclose, provided it is presented in a fair-balanced manner. Also, please avoid discussing product or development costs and do not make cost comparisons.
The article should be 2,500-3,500 words and must include at least five references or items for recommended reading.
We encourage images and/or data tables and have space for three or four of them. We’re flexible about that number so let us know if you need more image space. We also like to publish an additional photo or illustration at the beginning of the article. Images should be sent as separate files that meet the following specifications: high resolution, 300 dpi at a size of 7 x 7 inches and in only JPG, TIF or EPS formats.
Please be aware, due to copyrights, if you use figures or tables from articles that have been previously published in other journals, you must obtain permission from those journals in order to use the images. If you are an author on the published article in question, you may still need permission but there should be no fees from the other journal. If you are not an author and the other journal wants to charge you fees for usage, please contact us before proceeding. We do not want authors incurring costs in order to publish in Inhalation and there may be alternate approaches to citing information that could be used. Also, “open journals” do not charge for image use. If you have any questions or concerns, please contact us.
Editorial board review and production
All of our articles are peer-reviewed and must be accepted by our editorial board or a designated reviewer in order to be published. When you send us the article, it will go to a member of the board and we will coordinate communication between you. Once an article is accepted, we handle production and you will see the final article in layout before it goes to print or is published in the digital edition.
