Abstract
An apparatus and method is disclosed for forming a compacted powder slug coated with a film. The powder, e.g. of a medicament, is compacted and enrobed to produce compacted powder slugs by preferably mechanically compacting a powder and forming a film of a material, preferably hydroxy propyl methyl cellulose, by vacuum or pressure differential, about the surface of the powder thus compacted.
Claims15
An apparatus for forming a compacted powder slug coated with a film, comprising:
- a platen having a pocket for receiving a vacuum formed film into the pocket and receiving a powder;
- and
- a mechanical means comprising a compression piston for compacting the powder in said pocket, the compression piston having a front face with a concave recess and a square edge around the circumference of the front face.
An apparatus of claim any one of the preceding claims wherein the platen further comprises an aperture to allow a vacuum to be formed between the platen and the film.
