Title: A Randomised, Double-blind, Double Dummy, 3 Way Crossover Study Evaluating the Effects of a Combination of Seretide 50/500mcg Twice Daily Plus Tiotropium Bromide 18mcg Once Daily Compared With the Individual Agents (Tiotropium Bromide 18mcg Alone and Seretide50/500mcg Alone) in the Treatment of Subjects With COPD
Brief Summary: This study was designed to evaluate the effects on lung function of a combination of SERETIDE 50/500mcg twice daily plus tiotropium bromide 18mcg once daily compared with the individual treatments (tiotropium bromide 18mcg once daily alone and SERETIDE 50/500mcg twice daily alone) in subjects with COPD. The study will utilise a three-way cross-over design with a 2-week wash-out period between each 2-week consecutive treatment period.

* Patients aged 30 years or older
* Current or previous cigarette smoker with a history of cigarette smoking of ≥ 10 pack-years: number of pack years = (number of cigarettes per day/20) × number of years smoked) (e.g., 10 pack-years is equal to 20 cigarettes per day for 10 years, or 10 cigarettes per day for 20 years). Previous smokers are defined as those who stopped smoking at least 3 months prior to the study visit.
* Willing and able to provide written informed consent prior to study participation (on day of study visit).
* Able to read, write, and comprehend information in English.

Exclusion Criteria:

* Prior to enrollment, prospective subjects will be screened. A subject will be excluded from the study if he/she meets any of the following criteria:
* Regular use (i.e., prescribed for use on a daily basis) of the following respiratory medications within the 4 weeks prior to the study visit:

  * Ipratropium (Atrovent, ipratropium bromide)
  * Ipratropium/albuterol combinations (e.g., Combivent)

* Current participation in a respiratory-related research study and receiving experimental medications.
* Limited ability to provide a valid informed consent due to serious uncontrolled psychiatric disease, intellectual or cognitive deficiency, poor motivation, current substance abuse (including drugs and alcohol), or other relevant condition that, in the opinion of the site principal investigator, will interfere with the subject's participation in the study.
* Pregnant females.
* Any medical or physical condition such as acute respiratory infection that would interfere with the adequate performance of spirometry.
* Participating investigator, sub-investigator, study coordinator, employee of the participating investigator, or family member of the aforementioned site staffs.
