Design outcomes

Primary

MeasureTime frame
Timepoint(s) of evaluation of this end point: .;Main Objective: To assess the actions of levodropropizine on respiratory centre output in normal subjects and in patients with chronic cough.;Secondary Objective: To compare the central action of levodropropizine with that of codeine, an effective, centrally acting anti-tussive agent with a recognised depressant activity on the respiratory neurones. ;Primary end point(s): Changes in inspiratory drive as assessed by comparing changes in the mean inspiratory flow, the pressure during airway occlusion, minute ventilation and inspiratory muscle activity during CO2 rebreathing challenges in control conditions and following administration of each study drug.

Secondary

MeasureTime frame
Secondary end point(s): Changes in patient’s subjective perception of cough frequency and severity as assessed by means of standard scoring scales (Visual Analog Scale, VAS).;Timepoint(s) of evaluation of this end point: .
