Formoterol and Salmeterol in Partially Reversible Chronic Obstructive Pulmonary Disease: A Crossover, Placebo-Controlled Comparison of Onset and Duration of Action

Abstract

In conclusion, this study revealed that a single dose of 12 microg formoterol and 50 microg salmeterol provided comparable bronchodilation within 12 h and had tolerable side effects in patients with mild to severe COPD having partially reversible airway obstruction.
