As for the dry powder inhalator, the medicine chamber which includes the formulation which contains the carrier particle and the action medicine particle, to have the retention component which is approached to the mouthpiece, and the aforementioned mouthpiece which are let flow to the user directly it is possible the aforementioned action medicine particle. The aforementioned retention component while to make that the aforementioned action medicine particle flows to the user possible, makes size and the arrangement which obstruct that substantially all carrier particles flow to the user. To include the formulation which contains the carrier particle in order to convey the action medicine to lung system of the patient it is possible the aforementioned inhalator. As for the aforementioned carrier particle, it is possible to possess the average sieve diameter which exceeds approximately 500 millimicrons. Polystyrene, PTFE and the silicone glass, to be 1 kinds of silica gel, and quartz glass it is possible the aforementioned carrier particle.ドライパウダー吸入器は、キャリア粒子と作用剤粒子を含有する製剤を含む薬物チャンバー、前記作用剤粒子をユーザーに直接流すマウスピース、及び前記マウスピースに近接した保持部材を備えることができる。前記保持部材は、前記作用剤粒子がユーザーに流れることを可能にしながら、実質的に全てのキャリア粒子がユーザーに流れることを阻むサイズと配置にされる。前記吸入器は、患者の肺系統に作用剤を搬送するためのキャリア粒子を含有する製剤を含むことができる。前記キャリア粒子は、約500μmを超える平均篩径を有することができる。前記キャリア粒子は、ポリスチレン、PTFE、シリコーンガラス、シリカゲル、及びシリカガラスの1種であることができる。
