ABSTRACT:
A dosage form comprises at least one active ingredient, a first portion which comprises an exterior surface and one or more cavities defining at least one interior surface having indentations and an exterior surface, and a second molded portion which is inlaid into the cavities of the first portion and has an exterior surface. The first and second portions are in contact at an interface, the second portion comprises a solidified thermoplastic material, and the second portion resides substantially conformally upon the indentations of the first portion. In another embodiment, a dosage form comprises at least one active ingredient, a core having an outer surface and a shell residing on at least a portion of the core outer surface, wherein the shell comprises a first shell portion and a second molded shell portion which is inlaid into the first shell portion. In another embodiment, a dosage form comprises at least one active ingredient, a core, and a shell having a first molded shell portion which is discontinuous, and a second molded shell portion which is continuous, such that the discontinuities of the first shell portion are due to the presence of the second molded shell portion, and the first and second shell portions are compositionally different.
