Influence Of Different Airflow Resistances On Drug Effect Of 50μg Salmeterol And 6 μg Formoterol

Asthma Clinical Trial

Official title:
Single-Centre Randomised Open Crossover Study to Examine the Influence of Different Internal Resistances of Discus and Turbohaler Respectively on the Effects of Salmeterol and Formoterol in Asthmatic Subjects

Clinical Trial Summary

Effect of inhaled drugs administered as dry powder is not only dependent on drug efficacy but also on technical properties of the inhalers. Different inhalers have different internal resistances and therefore it is expected that patients with limited airflow may have different exposure rates of drugs delivered from different devices
