        • Stable state. Patients without exacerbations and without change in the previous treatment for at least 4 weeks prior to the visit 1 as defined by clinical history.
        • Comorbidities. No concomitant severe comorbidities which could interfere with study conduct, influence the interpretation of study observations/results, or put the patient at increased risk during the study observations/results, or put the patient at increased risk during the study.
        • Current Therapy: Patients needing combination ICS/LABA already in treatment with PDI (Turbohaler) or Diskus.
        • Short-Acting beta2-Agonists: All patients must be able to replace their current short-acting beta2-agonists with albuterol/salbutamol inhalation aerosol at the visit 1 for use as needed for the duration of the study.
        • Patients must be able to withhold all inhaled short-acting betapathomimetic bronchodilators for at least 6 hours prior to all study visits.
        • Capable of understanding the requirements, risks, and benefits of study participation, and, as judged by the investigator, capable of giving informed consent/assent and being compliant with all study requirements (visits, record-keeping, etc.).
        Exclusion Criteria:
        • Asthma severity. History of life-threatening asthma that is defined for this protocol as an asthma episode that required intubation and/or was associated with hypercapnia, respiratory arrest or hypoxic seizures.
        • COPD severity. COPD with a pre-bronchodilator FEV1 < 30% and/or FEV1 30-50% but requiring long term oxygen therapy.
        • Exacerbations. Any asthma/COPD exacerbation within one month of the visit 1. A patient must not have had any hospitalisation for asthma/COPD within 6 months prior to the visit 1.
        • Respiratory infections. Culture-documented or suspected bacterial or viral infection of the upper or lower respiratory tract, sinus, or middle ear that is not resolved within 2 weeks prior to the visit 1.
        • Comorbidities. Historical or current evidence of a clinically significant comorbidity including, but not limited to: cardiovascular (e.g. congestive heart failure, known aortic aneurysm, clinically significant cardiac arrhythmia or coronary heart disease), hepatic, renal, hematological (e.g. immunologic compromise), neuropsychological, endocrine (e.g. uncontrolled diabetes mellitus, uncontrolled thyroid disorder, Addison's disease, Cushing's syndrome), gastrointestinal (e.g. poorly-controlled peptic ulcer, gastroesophageal reflux disease), pulmonary (e.g. bronchiectasis with the need for treatment, cystic fibrosis, bronchopulmonary dysplasia, lung cancer) or history of a positive test for HIV, hepatitis B or hepatitis C infection. Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the patient at risk through participation, or which could affect the efficacy or safety analysis if the disease/condition exacerbated during the study.
        • History of any adverse reaction. History of any adverse reaction including immediate or delayed hypersensitivity to any beta2-agonist, sympathomimetic drug, or any intranasal, inhaled, or systemic corticosteroid therapy. Known or suspected sensitivity to the constituents of the inhalers used in the study (e.g. lactose in the dry powder inhalers).
        • Use of immunosuppressive medications. Use of immunosuppressive medications within 12 weeks prior visit 1 and during the study, including use of systemic corticosteroids. Immunotherapy at a stable dose for at least 90 days prior to the visit 1 and throughout the study for the treatment of allergies is permitted.

        • Concomitant participation to other research study. Participation to another research study investigational drug study within the 30 days (starting at the final follow-up visit) preceding the visit 1 or planned participation in another investigational drug study at any time during this study.
        Asthma and Chronic Obstructive Pulmonary Disease (COPD) are common conditions with an increasing prevalence worldwide. Inhaled therapy for these conditions has a number of advantages over systemic therapy, including reduced side effects and quicker onset of action.

        However, poor asthma control is common, despite available effective treatment .This is partially related to low adherence and to difficulties in using inhaler devices. Among patients with chronic respiratory disorders, 18% discontinued the prescribed inhaler treatment because of troubles with the device (Santus 2012). Some devices are not easy to handle, or require breathing abilities, which reduce the effectiveness in real life, especially in elderly.Since mistakes in inhaler technique are very common affecting drug delivery and efficacy, a correct inhaler technique training is fundamental. A single site study in 2012 (Press 2012) found that patients given verbal and written instructions followed by demonstrations of inhaler use had better inhaler technique than patients given verbal and written instructions only. The authors concluded that larger multi-centred studies were needed to evaluate hospital-based-education.

        Proposals to improve inhalers use are based on three key points:

        - the choice of the best device paying attention to patient needs and abilities (personalized therapy)

        - a complete explanation of the correct use (patient training)

        - a regular re-check to evaluate the maintenance of a correct technique (monitoring)

        The study consists of two phases:

        - A cross over phase: 3 periods of 1 week each. During the training visit at the beginning of each week period, patients will be instructed on the correct use of one of the 3 devices. Correct use and maintenance of correct use after 1 week will be assessed.

        - A longitudinal phase: patient will be treated with the last inhaler device used during the cross over phase for 8 additional weeks.

        The maximum time from screening to end of study visit is12 weeks, with a follow up taking place 30 days after the final visit .
