This is an interventional treatment trial for COPD focused on measuring Inhalers, Tiotropium
Eligibility Criteria
Inclusion Criteria:
- COPD patients with FEV1/FVC <70% predicted.

Arm Description
Patients receiving Handihaler who have not been trained (real-life use) for over 3 months on its use. Here the investigators want to see that if patients have on-going symptoms but are on Handihaler-Tiotropium 18mcg what is happening PRIOR to proper inhaler technique training - that is their 'real-life' use of the inhaler - to their lung function (large and small airways) and also symptoms or exercise limitation (determined by CAT score) will already be recorded as entry criteria
Patients will be trained in their use of Handihaler-Tiotropium and asked to take 18 mcg once daily for 14 days to see if their (i) airway lung function and or (ii) clinical symptoms improve. Here the investigators want to see what happens AFTER proper inhaler technique training on large and small airways lung function and also symptoms or exercise limitation (determined by CAT score)
Patients will be switched to trained Respimat Tiotropium 5 mcg once daily for 14 days to see if their (i) airway lung function and or (ii) clinical symptoms improve. Here the investigators want to see what happens AFTER this efficient device Respimat (trained) compared to PREVIOUS device Handihaler (trained) on large and small airways lung function and also symptoms or exercise limitation (determined by CAT score). The investigators want to see if the properties of the Respimat device with deeper lung deposition (slow velocity and small particles) can improve small airway measures (and indeed large airway measures) that might also be related to an improvement in symptoms.
Outcomes
Primary Outcome Measures
Peripheral Airways Resistance (R5-R20)
Peripheral airways resistance measured by impulse oscillometry (IOS). Specific frequencies relate to different levels: a frequency of 5 hertz (Hz) provides values for total airway resistance (R5) and reactance (X5); a 20Hz frequency gives a value for central or large airway resistance (R20); and if one subtracts the value of central airway resistance from that for total airway resistance (i.e. R5-R20), this provides a measure of peripheral or small airways resistance.
Secondary Outcome Measures
Sacin
After treatment Impulse Oscillometry parameter. Sacin is a gas exchange measures, assessing convectional ventilation heterogeneity in pre acinar/acinar airways.
Lung Function FEV1
After treatment period the lung function parameters FEV1
Multi-Breath Washout Test (MBW), Scond
After the treatment period the MBW parameters. Scond is a gas exchange measures, assessing convectional ventilation heterogeneity in peripheral conducting airways.

5. Study Description
Brief Summary
The aim of the study is to investigate the effect of tiotropium from different devices on a panel of small (IOS, MBNW, DLCO, FVC) and large airway (FEV1, PEF) responses in patients with mild-moderate COPD. Comparisons will be made between Tiotropium Handihaler 18 micrograms once daily and Tiotropium Respimat 5 micrograms once daily
Detailed Description
Patients with asthma and chronic obstructive airways disease (COPD) undergo routine testing of their lung function in the diagnosis, progression, management and, response to treatment of their disease. Standard lung function obtains measurements based on the forced flow of air moving within the airways. Such measurements give a reasonable assessment of disease affecting the large airways, but not an accurate estimate of small airways disease. Small airways are less than 2mm in diameter. However, both asthma and COPD have disease that involves not only the large but also the small airways that has important clinical consequences. Indeed, COPD predominantly affects the small airways.
Tiotropium (Spiriva, Boehringer Ingelheim), a long-acting inhaled anticholinergic bronchodilator, improves lung function, quality of life, and exercise endurance and reduces exacerbations in patients with chronic obstructive pulmonary disease (COPD).
Respimat Soft MistTM Inhaler (SMI) is a novel inhaler delivering a unique slow-moving Soft MistTM that allows gentle inhalation - making it easy to inhale. Importantly it has drug particles that are ~ 2microns that allow an increase in the total lung deposition of drug (~52%) and also the potential for penetration to treat the small and large airways in patients with COPD; that is targeting the whole airway tree.
RESEARCH AIM & HYPOTHESIS The aim is to investigate the effect of tiotropium from different devices on a panel of small (IOS, MBNW, DLCO, FVC) and large airway (FEV1, PEF) responses in patients with mild-moderate COPD. The investigators will compare Tiotropium Handihaler 18 micrograms once daily with Tiotropium Respimat 5 micrograms once daily.
The investigators will identify a COPD cohort with ongoing symptoms or exercise limitation on HandiHaler, as proposed. The science behind this is why are people still limited (even if partially as determined using the CAT score) and is more distal airway targeting necessary? This doesn't necessarily mean targeting the acinar/alveolar beyond the terminal bronchioles, but just a little bit deeper into the distal conducting airway. This can be achieved with Respimat.
