[Problems] The present invention provides a method for producing powders for inhalation in which deviation is less in the distribution and the dispersibility is excellent. [Solutions] The present invention relates to a method for producing powders for inhalation, comprising: a first mixing step of stirring a first active ingredient and a carrier in a presence of a milling medium, and mixing the first active ingredient and the carrier while crumbling the agglomerates of the first active ingredient to obtain a mixture of the carrier and the first active ingredient； and a second mixing step of adding fine powders to the mixture obtained in the first mixing step, and stirring and mixing the mixture and the fine powders in a presence of a milling medium.【課題】 有効成分が均一に分布し，しかも分散性に優れる吸入用パウダーの製造方法を提供する。【解決手段】 本発明は，第１の有効成分と担体を粉砕媒体の存在下に撹拌し，第１の有効成分を解砕しつつ，担体と混合することで担体及び第１の有効成分の混合物を得る第１の混合工程と，第１の混合工程で得られた混合物に，微粒粉体を添加し，粉砕媒体の存在下に撹拌混合する第２の混合工程と，を含む，吸入用パウダーの製造方法に関する。【選択図】図１
