Résumé
Glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI), formulated using co-suspension delivery technology, is the only approved fixed-dose combination long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) delivered via MDI. Direct comparisons of GFF MDI versus other LAMA/LABAs have not previously been performed. We assessed the efficacy and safety of GFF MDI relative to umeclidinium/vilanterol dry powder inhaler (UV DPI) in patients with moderate-to-very severe chronic obstructive pulmonary disease (COPD).
