Process for the preparation of fine particle pharmaceutical formulations

摘要

A process for preparing fine particle pharmaceutical formulations having improved throughput and producing greater uniformity of particle size. The process relates to adding to the dry components of the formulation prior to the steps of wetting, extrusion and spheronization, an extrusion aid material selected from pharmaceutically acceptable oils and waxes having a drop point between about 15 DEG C. and 115 DEG C.
