Effect of Symbicort on GR Localisation in Asthma
Effect of Symbicort on GR (Glucocorticoid Receptor) Translocation in Induced Sputum in Comparison With Budesonide, Formoterol and Placebo. A Single Dose Exploratory Study in Patients With Mild Asthma

To investigate a possible interaction between formoterol and budesonide on GR-translocation and to compare the effect of different doses of Symbicort (80/4.5 and 2x80/4.5 mcg) with the effect of budesonide (200 mcg and 800 mcg) on GR translocation, and to investigate the effect of the study drugs on exhaled NO (bronchial and alveolar fraction.
