EXTENDED RELEASE SUSPENSION COMPOSITIONS

摘要

The present invention relates to extended release suspension compositions of an active ingredient. Said extended release suspension compositions comprise multiple coated cores of the active ingredient and a suspension base, wherein the suspension base generates a hypertonic condition such that there is no substantial change in the in-vitro dissolution release profile of the extended release suspension compositions upon storage for at least seven days. The invention also relates to processes for the preparation of said extended release suspension compositions.
