Effect of Salmeterol on Brain-Derived Neurotrophic Factor (BDNF) Concentrations in Asthma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00736801

Brief Summary:
BDNF has been linked to the pathogenesis of airway hyperresponsiveness in asthma. In this trial, the impact of a treatment with salmeterol and salmeterol / fluticasone on BDNF concentrations will be assessed in patients with asthma. The investigators hypothesize that salmeterol impacts on BDNF concentrations in patients with asthma.
