Lung Deposition of the BDP/Formoterol Combination Administered Via the NEXT DPI in Healthy, Asthmatic and COPD Patients
Lung Deposition of the BDP/Formoterol Combination Administered Via the NEXT DPI in Healthy, Asthmatic and COPD Patients
The purpose of this study is to investigate the lung deposition and distribution pattern of
 Beclometasone and Formoterol using a gamma-scintigraphic technique after inhalation of a
 single dose of 99mTc-radiolabelled BDP/formoterol fixed combination administered Via the NEXT
 DPI in healthy volunteers, asthmatic and COPD patients. Additionally, the systemic exposures
 to formoterol, BDP and its monopropionate metabolite (B17MP) will be investigated.
