    摘要： The invention includes a core-and-shell dosage form or unit in which the core contains API and in which the shell substantially governs the release such as by controlling diffusion of API through the shell. The shell may comprise a release-blocking polymer, and particles of a release-regulating polymer. The shell may be substantially impervious but the release-regulating polymer may become suitable to allow diffusion through it when activated. The core may include a buffer region between the shell and the API-containing portion of the core. The dosage form may include multiple units. The dosage form of the invention is capable of providing a release profile whose time scale can be adjusted by adjusting powder composition, and which may be approximately zero-order release. The invention further includes methods of manufacturing such a dosage form, such as three-dimensional printing.

    摘要： A drug delivery device such as an oral dosage form (ODF) with a toxic or potent core encapsulated by a non-toxic region. The non-toxic region may be a region including multiple layers, coatings, shells, and combinations thereof, which provides protection to and isolation from the toxic or potent core. The drug in the toxic or potent core is incorporated into the dosage form via, for example, three-dimensional printing, as a solution, solubilization or suspension of solid particles in liquid, rather than by the more conventional handling and compressing of dry powder. This minimizes the likelihood of creating airborne particles of the toxic drug during manufacturing, hence controlling and minimizing the exposure of manufacturing personnel to the hazardous substance. Wet dispensing of the toxic or potent drug further provides greater bioavailability of the drug to the patient.
