Inhaler Lung Deposition in Chronic Obstructive Pulmonary Disease (COPD)

"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."
