FIELD: medical engineering.
SUBSTANCE: method involves collecting fine powder on dosing unit surface as elongated doses. Single use dosing unit has several prefabricated dose strips to which access is provided. The dosing member having corresponding opening moves along elongated strip of the dosing unit when introducing drug increasing in this way time interval spent for releasing pharmaceutical composition from the dosing unit into inhalator air flow near the entry. Relative movement of the dosing member is achieved by rotating the dosing unit itself or by moving the dosing member along dosing unit surface.
EFFECT: uniform powder distribution when moving along elongated dose strip during 1-2 s long inhalation.
