Abstract

The present invention provides a powder inhaler (10) for administration of a unit dose of a medicament (36), said powder inhaler comprising: (A) Walls (14, 16) enclosing at least one chamber (12) comprising a medicament containing recess at one end and a channel extending from the medicament containing recess to the air outlet hole (34); (B) Air inlet hole(s) (24) located near the medicament containing recess; (C) An air outlet hole (34); and (D) Means (20, 21, 32) for sealing said air inlet (24) and outlet holes (34), wherein the location of the air inlet hole(s) (24) with respect to the medicament containing recess is such that upon inspiration by the patient, the air stream directly impacts the powder bed, entrains the particles and carries them to the air outlet (34) for inspiration by the patient.
