ABSTRACT:
An inhalation device having an elongate housing having one or more passageways for the passage of air therethrough. Each passageway, of relatively small diameter, opens into an emptying chamber, of relatively greater diameter, adjacent that end of the housing which is adapted for insertion into the mouth or nose of a user. Adjacent that end of the emptying chamber closest to the passageway(s), the housing has means for receiving or presenting a unit dose of powdered medicament for administration. Means are provided to open the medicament holder as it is being inserted into, or after it has been inserted into, the means for receiving or presenting a unit dose of powdered medicament for administration. During inhalation, the air stream passing over and directed into the powdered medicament holder entrains the powdered medicament which is then carried into the nose, throat or lungs of the user where beneficial or therapeutic action of the medicament occurs.
