asthma, quality of life, lung function
All Asthmatics will be treated with 1 of 3 long acting beta 2 agonist + corticosteroid using low or medium dose of inhaled (Advair) fluticasone or equivalent corticosteroid 200-500mcg/day plus salmeterol 100 mcg/day or (Symbicort) budesonide 320-640 mcg +formoterol 18 mcg/day or (Dulera) mometasone 400-800mcg + formoterol 20 mcg/day. In addition tiotropium 18ucg/day will be used. Additionally, albuterol 0.083%/ipratropium 0.02% solution or MDI HFA for acute exacerbation.Will measure lung function and asthma quality of life questionaire
