Randomized Controlled Trial Multicenter StudyEfficacy and safety of formoterol fumarate delivered by nebulization to COPD patients.
Nebulized solutions of long-acting bronchodilators provide an alternative to DPI and MDI delivery, particularly for COPD patients unable to use hand-held devices easily or correctly. The long-acting beta2-agonist, formoterol fumarate, is differentiated by its onset of significant bronchodilation within 5 min of administration. In a randomized, double-blind, double-dummy trial, COPD subjects (n=351, mean forced expiratory volume FEV1=1.3 L, 44% predicted) received nebulized formoterol fumarate (Perforomist inhalation solution; FFIS 20 microg) or DPI (Foradil Aerolizer; FA 12 microg), or placebo twice daily for 12 weeks. ⋯ Drug related AEs in the FFIS arm with a frequency > or = 1% and exceeding placebo were dry mouth, nausea, and insomnia. Nebulized FFIS provided significant improvement in respiratory status and quality of life in subjects with COPD relative to placebo and was well tolerated. The efficacy and safety profile of FFIS was comparable to FA DPI.
