Abstract
The present invention provides an improved process for the preparation of a agglomerated solid dosage form, comprising: (1) preparing an aqueous slurry of (a) microcrystalline cellulose; (b) a microcrystalline cellulose compressibility augmenting agent which (i) physically restricts the proximity of the interface between adjacent cellulose surfaces; (ii) inhibits interactions between adjacent cellulose surfaces, for example, via the creation of a hydrophobic boundary at cellulose surfaces; or (iii) accomplishes both (i) and (ii) above; and (c) an active agent; (2) thereafter drying the resultant aqueous slurry in a manner which inhibits quasi-hornification, thereby obtaining an agglomerated material which is directly compressible into a solid dosage form.
