Primary Outcome Measures
NameTimeMethod
Main Objective: To determine whether extra-fine preperations of inhaled beclometasone dipropionat e preferentially suppress inflammation in small airways, over standard 'coarse' preperations in asthmatic subjects. To determine whether the oral anti-inflammatory agent Singulair confers additional benefit over and above that afforded by inhaled corticosteroids on small airway infllammation. The degree of inflammation will be quantified using the surrogate inflammatory marker nirtic oxide.<br>;Secondary Objective: To quantify the effects of both extra-fine and standard formulations of inhaled beclometasone dipropionate on surrogate markers of inflammation, and respiratory function;Primary end point(s): Concentration of exhaled Nitic oxide before and after treatment with:<br>1. Extra-fine formulations of beclometasone dipropionate<br>2. Standard formulations of beclometasone dipropionate<br>3. Extra-fine beclametasone dipropionate plus oral motelukast
