Novel dry powder inhalation for lung-delivery and manufacturing method thereof

摘要

The present invention provides marked results in that it is possible to present by a simple method a dry powder inhalation for pulmonary delivery that is made from a biologically active substance in crystal form and a biocompatible, electrostatic aggregation-inhibiting substance and that has excellent safety, stability, and pulmonary delivery performance. Moreover, it is also possible to provide sustained release performance that is appropriate for the properties of the biologically active substance by selecting [the appropriate] hydrophobic substance.
