CA2819663A1 — Rapidly dispersing granules, orally disintegrating tablets and methods

USPTO Abstract

This invention relates to rapidly dispersing microgranules comprising at least one sugar alcohol or saccharide, at least one super disintegrant, and a pharmaceutically acceptable additive with multi-functionality (e.g., starch acting as a binder, disintegrant, diluent/filler, glidant, etc) at a low level, which can be formed by not only eliminating a wet milling step but also avoiding an extensive dry milling step. Furthermore, such rapidly dispersing microgranules could also comprise a pharmaceutically active agent thereby providing for a pharmaceutical composition, or the rapidly dispersing microgranules thus produced are suitable for blending with a pharmaceutically active agent that is optionally taste-masked and/or controlled release coated microparticles to also provide for a pharmaceutical composition and the invention is also directed to a method for manufacturing such rapidly dispersing microgranules in a high useable yield, as well as orally disintegrating tablets comprising such rapidly dispersing microgranules. The rapidly dispersing microgranules are also free flowing.
