Abstract
A medicament compact is produced by placing loose powdered medicament in a mould having a longitudinal axis where a mandrel is positioned along the longitudinal axis of the mould compressing the medicament when a force parallel to the longitudinal axis is applied. The frictional force between the medicament and the mould and the frictional force between the medicament and the mandrel are opposite. Apparatus and compacted medicaments are also disclosed,
Claims8
A process for the production of a medicament compact, comprising the steps of:
- a) placing loose powdered medicament in a mould (3) having a longitudinal axis,
- b) positioning a mandrel (2) along the longitudinal axis of the mould (3);
- and
- c) compressing the medicament by applying a force parallel to the longitudinal axis such that during compression the frictional force between the medicament and the mould (3) and the frictional force between the medicament and the mandrel (2) are in opposite directions parallel to the longitudinal axis.
