Abstract
A drug composition comprising a coated bead is used in the manufacture of immediate release and/or controlled release drug compositions. In a specific embodiment, the bead includes an inert core of a water-soluble or water-swellable material, which has been coated with a seal layer formed from a non-polymeric hydrophobic material. The immediate and/or controlled release beads may be used to form tablets or capsules. A method of making the beads by sequential deposition of multiple layers on the inert cores is also described.
