Title: Randomised Cross-over Study to Compare the Effect of Formoterol Plus Tiotropium Versus Formoterol Monotherapy on Breathlessness, Dynamic Hyperinflation and Exercise Tolerance in Moderate-to-severe Stable COPD Patients
Brief Summary: The primary objective is to comparatively evaluate the isolated effects of a long-acting beta2-adrenergic (formoterol fumarate 12µg b.i.d. via Aeroliser) and combined with a long-acting anti-cholinergic (tiotropium bromide 18µg o.d via Handihaler) on breathlessness, dynamic hyperinflation and exercise tolerance in patients with advanced, but stable, chronic obstructive pulmonary disease. The study hypothesis is that combining long acting bronchodilators with different action mechanisms would promote synergistic effects on clinical outcomes.
