ABSTRACT:
A carrier impregnated at spaced locations along its circumference with a dose of powdered medicament. The carrier is selectively indexed so as to present the impregnated doses of medicament seriatim between a pair of holes in an upper and lower pressure plate in an inhalator. Air is forced through the holes in the pressure plates and the encapsulated dose on the carrier to entrain a dose of the powdered medicament, which is then inhaled through a mouthpiece, by the patient-user. The powdered medicament is embedded in and across interstices in the carrier formed by intersecting and sometimes offset depressions on each surface of the carrier, providing corners and surfaces to cause the medicament entrained in the air stream to break up as it is pressed up against and passed through the carrier infrastructure to aerosol or atomize the same so that the medicament is presented in appropriate particle sizes for maximum benefit when inhaled.
