Abstract

A powdered pulmonary surfactant preparation containing a hydrophobic protein serving as a pulmonary surfactant is obtained by spray drying an organic solution or suspension containing a hydrophobic protein serving as a pulmonary surfactant and possibly other components. Obtained power preparations exhibit very good stability under storage, are easy to reconstitute and are also suitable for administration by inhalation.
