Variability of fine particle dose and lung deposition of budesonide delivered through two multidose dry powder inhalers

Abstract

Thus, this study showed that device N is likely to improve the reliability of inhalation therapy by reducing both the variability of the delivered drug and that of the lung deposition. The reliability of inhalation therapy and consequently the quality of long-term control of asthma and the patient's compliance might improve when choosing the DPI with the better characteristics.
