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.
本发明提供了一种制备团聚固体制剂的改进工艺,包括(1) 制备由以下物质组成的
水性浆料:(a)
微晶纤维素;(b)
微晶纤维素可压缩性增强剂,其(i) 物理限制相邻
纤维素表面之间界面的接近;(ii) 抑制相邻
纤维素表面之间的相互作用,例如通过在
纤维素表面形成疏
水边界;(c) 一种活性剂; (2) 随后以抑制准角化的方式干燥所得到的
水浆,从而得到可直接压缩成固体剂型的团聚材料。
