Eligibility criteria:

        Inclusion Criteria:

          -  Caucasian male or female subjects aged 40-75 years inclusive. The need to recruit only
             Caucasian subjects is related to the need to rigorously exclude 2D6 poor metabolisers
             based on genotype.

          -  Female subjects must be of non-childbearing potential.

          -  An established clinical history of COPD (ATS/ERS definition).

          -  'Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease
             characterised by airflow limitation that is not fully reversible. The airflow
             limitation is usually progressive and is associated with an abnormal inflammatory
             response of the lungs to noxious particles or gases, primarily caused by cigarette
             smoking. Although COPD affects the lungs, it also produces significant systemic
             consequences.'

          -  Subject is a smoker or an ex-smoker with a smoking history of at least 10 pack years
             (1 pack year = 20 cigarettes smoked per day for 1 year or equivalent).

          -  Subject has FEV1/FVC < 0.7 post-bronchodilator (salbutamol) dose.

          -  Subject has 40 ≥ FEV1 ≤ 80% of predicted normal for height, age and gender after
             inhalation of salbutamol dose.

          -  Response to ipratropium bromide.

          -  Subject is able and has given written informed consent to take part in the study.

          -  Subject is available to complete all study measurements and procedures.

          -  Subject's BMI is 18.0 - 32.0 kg/m2.

          -  Subjects have a 24hr Holter recording that is within normal limits and does not
             demonstrate any clinically important abnormality that, in the opinion of the
             investigator, would make the subject unsuitable for participation in the study

        Exclusion Criteria:

          -  Subjects who have a past or present disease of any organ system, which as judged by
             the Investigator, may affect the outcome of this study.

          -  The subject has a positive pre-study drug screen. A minimum list of drugs that will be
             screened for include Amphetamines, Barbiturates, Cannabis, Cocaine and Opiates. The
             detection of drugs with a legitimate medical use would not be an exclusion to study
             participation.

          -  The subject has a positive pre-study alcohol screen. The detection of alcohol would
             not be an exclusion at screening but would need to be negative pre-dose and during the
             study.

          -  A suspected history of alcohol abuse within the six months previous to the screening
             visit.

             or HIV (if determined by local SOP's).

          -  Subject has received an investigational drug within 30 days of screening.

          -  The subject is currently taking medication which is known to be a CYP 2D6
             inhibitor/substrate.

             intends to donate during the study.

          -  The subject has a known allergy or hypersensitivity to ipratropium bromide, tiotropium
             bromide, atropine and any of its derivatives or lactose/milk protein.

          -  Subject is unable to use the DISKUS™/HandiHaler devices correctly.

             glaucoma.

          -  Subjects with a 2D6 poor metaboliser genotype (Caucasian).

          -  The subject has claustrophobia that may be aggravated by entering the plethysmography
             cabinet (American Association of Respiratory Care 2001 guidelines for body
             plethysmography)

          -  Received antibiotic therapy for either a lower respiratory tract infection or for COPD
             exacerbation within the 4 weeks prior to Screening.

        Respiratory criteria

          -  Subject has a diagnosis of active tuberculosis, lung cancer, clinically overt
             bronchiectasis, allergic rhinitis, or asthma.

          -  Subject has poorly controlled COPD, defined as either: acute worsening of COPD that is
             managed by the subject at home by treatment with corticosteroids in the 6 weeks prior
             to screening visit Or more than two exacerbations in the previous 6 months prior to
             screening that required a course of oral corticosteroids or antibiotics, or, for which
             the subject was hospitalised.

          -  Subject has participated in a Pulmonary Rehabilitation Program within 4 weeks prior to
             screening visit or will enter a program during the study.

          -  Subject has had a respiratory tract infection in the 4 weeks prior to the screening
             visit.

        Cardiovascular criteria

          -  Current congestive heart failure (greater than NYHA I), myocardial infarction (within
             3-years of the screening date) or ischaemic heart disease requiring regular therapy

          -  A history of clinically significant arrhythmia or clinically important 24hr Holter
