Abstract
An inhalation device for transpulmonary administration comprises: a chamber (16) for containing a pharmaceutical composition which is pulverized into fine particles by an air-generated impact for dispersal in air; an air inlet flow path (2) for introducing to the chamber (16) outside air to apply the air-generated impact to the pharmaceutical composition and for injecting the outside air toward the pharmaceutical composition; an inhalation flow path (1) for inhaling the pulverized pharmaceutical composition; a housing (9) for accommodating the chamber (16), the air inlet flow path (2), and the inhalation flow path (1); a mouthpiece (10) provided at one end of the housing (9), the mouthpiece (9) being provided with a mouth-side flow path (11) which communicates with the inhalation flow path (1), and an auxiliary flow path (12).
