The environmental impact of inhaler replacement: A carbon footprint and economic calculation of the National Database of Health Insurance Claims in Japan

Journal of General and Family Medicine, 2023
Background Drugs are a major source of greenhouse gas (GHG) emissions from healthcare systems. Pressurized metered‐dose inhalers (pMDIs) have raised concerns over their environmental impact due to GHG emissions.

Dose proportionality of fluticasone propionate from hydrofluoroalkane pressurized metered dose inhalers (pMDIs) and comparability with chlorofluorocarbon pMDIs

Respiratory Medicine, 2000
Fluticasone propionate pressurized metered dose inhalers (pMDIs) containing the hydrofluoroalkane (HFA) propellant, HFA 134a, are being developed to replace existing chlorofluorocarbon (CFC) pMDIs. This is part of the ongoing worldwide project to limit the damage to the earth's ozone layer.The in vivo performance and dose proportionality of fluticasone

Fiberboard Made from Scrap Denim: Characterization of its Properties by Effective Bulk Modulus Elastography

BioResources, 2023
Fiberboards from scrap denim were fabricated using two different resins, melamine urea formaldehyde (MUF) and polymeric methylene diphenyl diisocyanate (pMDI). Resin content and MUF-pMDI weight ratio were studied. Physical and mechanical tests determined

Multi-physics theoretical approach to predict pMDI spray characteristics [PDF]

, 2016
Continued success in treatment of asthma and COPD requires development of new formulations, which may alter spray characteristics and atomisation quality of atomiser devices such as pMDI. Fundamental understanding of the underlying physical phenomena and

Hair analysis of formoterol as a novel tool to assess long‐term inhalation medication adherence: Data from the TRICOLON trial

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this paper is to examine inhaled formoterol concentrations in hair and assess the potential of hair analysis as a tool for measuring long‐term adherence, by validation with objective data from digital inhalers. Methods Hair samples and digital inhaler data were collected from patients with COPD in 10 hospitals in the Netherlands as part ...

Designing chiral organic small molecules for circularly polarized light detection via group theory

InfoMat, EarlyView.
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...
