The purpose of the study is to investigate, whether the FeNO concentration of asthmatic children is influenced differently by inhaled corticosteroid compared to inhaled corticosteroid + long acting beta agonist. The study hypothesis is that the FeNO concentration is more decreased in patients with a combination therapy compared to those with a corticosteroid mono therapy.
