The Effect of Baseline Rescue Medication Use on Efficacy and Safety of Nebulized Glycopyrrolate Treatment in Patients with COPD from the GOLDEN 3 and 4 Studies.

These results suggest that baseline rescue medication use assessments may be useful in the management of COPD. Treatment with nebulized GLY improved lung function and symptom scores, regardless of baseline rescue medication use. These results support the use of nebulized GLY for the treatment of COPD, independent of baseline rescue medication use.
