The invention relates to an inhaler for powdered drugs intended for patient to receive through an inhaled air stream containing at least one powder container, measuring means for repeatedly measuring the dose of powder from said container, a transition mechanism for moving said measuring device from the filling position for receiving a dose of powder in the empty position for the release of said dose of powder into the powder channel, at least one activating device property for manual actuation by the patient, functionally related to said transition mechanism, so that when activated, one dose of the powder is measured, said activating device comprising a dosing button (5), which, when actuated by the patient, has an effect on said transition mechanism. In accordance with the invention, said transition mechanism further comprises a metering lever (6) affecting said metering means, said metering lever (6) being locked in the inhalation position of said metering means after said metering button (5) is appropriately pressed by a patient . The metering lever (6) in the inhalation position engages with the trigger element and is disengaged by activating the trigger element. The trigger element comprises at least one curved surface, and the metering lever (6) is tangentially engaged with said curved surface in said locked inhalation position.Изобретение относится к ингалятору для порошкообразных лекарственных средств, предназначенных для приема пациентом посредством воздушного потока, вызываемого вдыханием, содержащему по меньшей мере одну емкость для порошка, мерное средство для многократного отмеривания дозы порошка из упомянутой емкости, механизм перехода для перемещения упомянутого мерного средства из положения заполнения для приема дозы порошка в положение опорожнения для выпуска упомянутой дозы порошка в канал для порошка, по меньшей мере одно активирующее устройство для ручного приведения в действие пациентом, функционально связанное с упомянутым механизмом перехода
