Summary

Patients with chronic obstructive pulmonary disease (COPD) experience breathing difficulties because the airways deep in their lungs become narrowed. COPD patients use inhaler drugs to provide relief from breathlessness. However, current inhalers are inefficient as they deliver a 'coarse-mist' of drug-droplets that do not reach the deep airways.

In our study, we will use an inhaler of 'fine-mist' drug-droplets, tagged with a radioactive tracer to track them. We will take images of the lungs to see if the fine-mist droplets reach the deep airways, and assess if this improves the breathing capacity in our patients. Our research may allow the development of new, more efficient inhalers to improve treatment for patients with COPD.

DRUG

SALBUTAMOL

In the LUNG DEPOSITION STUDY; SALBUTAMOL INHALED VIA RESEARCH NEBULISER at 3 PARTICLES SIZES OF 1.5 MICRONS, 3 MICRONS AND 6 MICRONS WILL BE GIVEN AT SLOW INHLATION AND AGAIN AT FAST INHALTION;DOSAGE- 30 MICROGRAMS, ONE SINGLE INHALATION ONLY. IN ADDITION, SALBUTAMOL AT 200 MICROGRAMS INHALED VIA A STANDARD METERED DOSE INHALER WILL ALSO BE GIVEN AS A SINGLE INHALATION. In the LUNG PHYSIOLOGY STUDY; SALBUTAMOL INHALED VIA RESEARCH NEBULISER at 3 PARTICLES SIZES OF 1.5 MICRONS, 3 MICRONS AND 6 MICRONS WILL BE GIVEN AT TWO DOSAGES OF 30 MICROGRAMS AND AGAIN AT 15 MICROGRAMS, ONE SINGLE INHALATION ONLY. IN ADDITION, SALBUTAMOL AT 200 MICROGRAMS INHALED VIA A STANDARD METERED DOSE INHALER WILL ALSO BE GIVEN AS A SINGLE INHALATION. ALL INHALATIONS WIL BE AT SLOW INHALTION IN THIS PART OF THE STUDY.
