Abstract
A dosage inhalator for the inhalation of a pharmacologically active compound in solid, micronized form is disclosed. The inhalator comprises a propellant container, a propellant dispensing unit, and a dosing unit for dosing the pharmacologically active compound. The dosing unit comprises a storage chamber for the active compound, a dose loading unit directly connected thereto, and a nozzle. The dose loading unit comprises a movable perforated membrane, and a holder for the perforated membrane. The membrane is displaceable between a first position where active compound is introduced into the perforations of the membrane, and second position where the perforations of the membrane are inserted into a propellant passage. While the membrane is in the second position, the propellant dispensing unit may be operated, allowing propellant originally stored in the propellant container to remove the active compound from the perforations inserted into the propellant passage and carry said compound out the nozzle.
