Abstract:
The invention relates to apparatus for filling a cavity during production of a pharmaceutical dosage form. The apparatus comprises a cavity open at an upper surface and closed at a lower surface. The lower surface is defined by an initial layer of powder. A powder source and a fluid pump are also provided. The fluid pump is arranged to draw gas away from the cavity such that the gas pressure within the cavity is reduced below the ambient gas pressure before the cavity is filled to a predetermined fill level with powder from the powder source.
