Abstract
Directly compressible, wax-containing granules having improved flow properties are obtained when waxes are admixed in the melt with certain flow improving additives, followed by cooling and granulation of the admixture. In certain embodiments of the invention, only the wax itself melts in the melt combination of the wax(es) and additives(s), and in other cases both the wax(es) and the additives(s) will both melt. In either case, the melt combination of the wax(es) with the additive(s) yields, upon cooling and granulation, a wax-containing particulate drug diluent having improved and unexpected flow properties.
