Introduction: FRI is a novel computational fluid dynamics (CFD)-based technique using formulation profile and patients lung CT scan to simulate aerosol deposition. Aims and objectives: To evaluate lung deposition of pressurized metered dose inhaler (pMDI) extrafine beclometasone dipropionate/formoterol fumarate/glycopyrronium (BDP/FF/G Trimbow®) with pMDI extrafine BDP/FF (Foster®) pMDI and compared them with reference gamma scintigraphy data. Methods: FRI was used to assess, in silico, the deposition of pMDI combination products (BDP/FF/G and BDP/FF) in 20 moderate to severe COPD patients. FRI combined high-resolution lung CT scans of each patient with in silico computational flow simulati…

Background: Functional respiratory imaging (FRI) is a computational fluid dynamics-based technique using three-dimensional models of human lungs and formulation profiles to simulate aerosol deposition. Methods: FRI was used to evaluate lung deposition of extrafine beclomethasone dipropionate (BDP)/formoterol fumarate (FF)/glycopyrronium bromide (GB) and extrafine BDP/FF delivered through pressurized metered dose inhalers and to compare results with reference gamma scintigraphy data. FRI combined high-resolution computed tomography scans of 20 patients with moderate-to-severe chronic obstructive pulmonary disease (mean forced expiratory volume in 1 second 42% predicted) with in silico comput…
