Brief Summary
The study aims to explore the effect of tiotropium on airway remodeling by using Endobronchial Optical Coherence Tomography (EB-OCT). We enrolled patients with GOLD I stage COPD. All the patients will be divided into four groups randomly to receive SABA as needed with or without regular use of tiotropium. Changes of airway morphology (accessed by EB-OCT), pulmonary function, QOL, and SABA usage will be obtained.

Study Arms (3)
Tiotropium (0-12 month) + SABA as needed
EXPERIMENTAL* During the 2 years treatment phase patients will be administered with tiotropium bromide (Spiriva) capsule 18μg once daily from baseline to the 12th months. * Any long acting bronchodilator will not be used from the 12 to 24 months. * Salbutamol sulphate aerosol (Ventolin) will be administered as concomitant medication treatment when exacerbation occurs.
Tiotropium (0-24 month) + SABA as needed
EXPERIMENTAL* During the 2 years treatment phase patients will be administered with tiotropium bromide (Spiriva) capsule 18μg once daily from baseline to the 24th months. * Salbutamol sulphate aerosol (Ventolin) will be administered as concomitant medication treatment when exacerbation occurs.
SABA as needed only
OTHER* During the 2 years treatment phase patients will be administered with salbutamol sulphate aerosol (Ventolin) when exacerbation occurs. * Any long acting bronchodilator will not be used during the 2 years treatment phase.
Interventions
Tiotropium bromide (Spiriva) capsule 18μg once daily inhaled.
As needed use of salbutamol sulphate aerosol (Ventolin) when exacerbation happens
