ABSTRACT:
The present invention is a process for forming a low density compression dosage unit to provide increased strength. The process of the present invention includes compacting under bi-level compaction pressure to provide a continuous-volume dosage unit which has a first volume defining an edge portion of the unit and a density which is greater than a density of a second volume defining a non-edge portion of the unit. The present invention also includes the product resulting from the process and apparatus used to make such units.
