摘要： A dosage form comprises: (a) at least one active ingredient: (b) a core having a first surface portion upon which resides a first coating and a second surface portion which is substantially free of the first coating; and (c) a shell which resides upon at least a portion of the second surface portion, wherein the shell comprises a different material from the first coating. In another embodiment, the dosage form comprises: (a) at least one active ingredient; (b)a core comprising a center portion having an exterior surface and an annular portion having an exterior surface and an interior surface, wherein the annular portion interior surface is in contact with at least a portion of the center portion exterior surface, and a coating resides on at least a portion of the annular portion exterior surface; and (c) a shell which resides upon at least a portion of the exterior surface of the center portion, wherein the shell comprises a different material than the impermeable coating. In another embodiment, the dosage form comprises: (a) at least one active ingredient; (b) a core having an outer surface and a cavity which extends at least partially through the core such that the core outer surface has at least a first opening therein; (c) a first coating which resides on at least a portion of the core outer surface, wherein the first shell portion comprises a different material from the first coating; and (d) a first shell portion which is adjacent to the first opening and covers at least the first opening.

摘要： A dosage form comprises: (a) at least one active ingredient; (b) a core; and(c) a shell which surrounds the core, wherein the shell is substantially free of pores having a diameter of 0.5-5.0 microns, and the shell comprises a first shell portion and a second shell portion which are compositionally different and the dosage form provides a modified release profile of the active ingredient upon contacting of the dosage form with a liquid medium. In another embodiment, the dosage form comprises: (a) at least one active ingredient; (b) a core comprising first and second core portions; and (c) a shell which surrounds the core, wherein the shell comprises first and second shell portions such that the first shell portion resides upon the first core portion and the second shell portion resides upon the second core portion, and at least one of the first or second shell portions or first or second shell portions provides a modified release profile of the active ingredient upon contacting of the dosage form with a liquid medium.
