RT Journal Article SR Electronic T1 Environmental impact of inhalers for respiratory diseases: decreasing the carbon footprint while preserving patient-tailored treatment JF BMJ Open Respiratory Research JO BMJ Open Resp Res FD British Thoracic Society SP e000571 DO 10.1136/bmjresp-2020-000571 VO 7 IS 1 A1 Sara Panigone A1 Federica Sandri A1 Rossella Ferri A1 Andrea Volpato A1 Elena Nudo A1 Gabriele Nicolini YR 2020 UL http://bmjopenrespres.bmj.com/content/7/1/e000571.abstract AB Patients with asthma and Chronic Obstructive Respiratory Disease (COPD) rely on three main device classes for inhalation therapy: metered-dose inhalers (MDIs), dry powder inhalers (DPIs) and soft-mist inhalers (SMIs). The carbon footprint (CF) of these inhalers differs with MDIs having a higher impact than DPIs and SMIs due to the propellant in MDIs. However, the certified CF of specific MDI products may differ significantly. MDIs still represent an essential option for many patients. Consequently, novel approaches shall be considered to balance environmental goals with patient health and well-being while maintaining a diverse range of choices for patients and physicians.
