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
