<qa>  What is the purpose of this study?Until now, most of the inhaled medications available have been made up of big particles that never reach the peripheral lung. The purpose of this study is to try to measure the level of inflammation in the peripheral lung in asthmatics and see if this inflammation can be decreased with different types of inhaled corticosteroids. The investigators will check airway inflammation before and after use of an inhaled corticosteroid that has a large particle size and should only reach the large airways Flunisolide-CFC, and before and after use of an inhaled, small particle corticosteroid that should reach both the large and small airways Flunisolide-HFA.
