Randomized Controlled Trial Multicenter StudyRandomized study of the effects of Aerochamber Plus® Flow-Vu® on the efficacy, pharmacokinetics and safety of glycopyrronium/formoterol fumarate dihydrate metered dose inhaler in patients with chronic obstructive pulmonary disease.
This study compared the efficacy, pharmacokinetics (PK), and safety of GFF MDI (Bevespi Aerosphere®), a fixed-dose combination of glycopyrronium and formoterol fumarate dihydrate (14.4/10 μg) delivered by a metered dose inhaler (MDI) formulated using innovative co-suspension delivery technology, in patients with moderate-to-very severe chronic obstructive pulmonary disease (COPD) with and without the Aerochamber Plus® Flow-Vu® valved holding chamber (VHC). ⋯ The magnitude of bronchodilatory effect was similar with and without a VHC following GFF MDI treatment. This, together with the PK and safety profiles, supports the use of the VHC with GFF MDI for the maintenance treatment of COPD, which could be particularly useful for patients who have difficulty with the coordination of an MDI.
