This invention relates to a dry powder medicament and particularly to a medicament which provides improved fine particle fraction. The method for preparing the inhalable dry-powder medicament comprises the steps of: (i) fractionating a particulate active ingredient based on aerodynamic particle size, (ii) recovering at least one fraction of the particulate active ingredient and (iii) combining the recovered fraction with a carrier to provide the inhalable dry-powder medicament. A dry-powder medicament per se is also described.
