    • A multipart capsule, e.g., a dosage form, is provided which includes a plurality of capsule portions, at least one of which contains a substance to be released into a gastro-intestinal environment and at least one link component interconnecting two adjacent capsule portions. At least one capsule portion is formed from a polymer that is a transitional polymer, for example, a polymer that changes shape, form, or structure within a gastro-intestinal environment, e.g., dispersible, dissolvable, disintegrable, fracturable, breachable, swellable, partially or completely soluble, or otherwise changeable when exposed to stomach pH and/or in intestine pH to thereby release the substance. The capsule portions are connected together in an assembled dosage form. The link component includes at least one aperture in flow communication with interiors of two adjacent capsule portions to control the release of the substance.
