Influence of a Inhaled Corticosteroid Therapy Versus Corticosteroid + LABA Therapy on the FeNO of Asthmatic Children
Influence of a Inhaled Corticosteroid Therapy Versus Corticosteroid + LABA Therapy on the FeNO of Asthmatic Children
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.
Inclusion Criteria:

 -  allergic asthma since > 6 months equal or lower corticosteroid therapy before study
 entry FEV1>50%

 Exclusion Criteria:

 -  severe asthma respiratory infection within the last 4 weeks smoking
