Residence structure and related method

Abstract

To provide a residence structure and a related method.SOLUTION: A residence structure, a system and a related method are provided. In a specific embodiment, a residence structure is administered (for example, oral administration) to a subject (for example, a patient) so as to hold the residence structure for a specific period (for example, almost 24 hours or longer) at an internal position of the subject before discharge of the residence structure. In some embodiment, the residence structure may be an intragastric residence structure. In some embodiments, the structure and the system herein comprise one kind or more kinds of materials which are formed for filling of high level active material (for example a remedy), stability of high active material and / or structure in an acidic environment, mechanical flexibility and intensity in an internal opening (for example, a gastric cavity), easy passage in a gastrointestinal tract to delivery to a desired internal opening (for example, a gastric cavity), and quick solution / decomposition in response to a physiological environment (for example, an intestine environment) and / or chemical stimulant (for example, taking a solution which induces quick solution / decomposition).SELECTED DRAWING: Figure 1A
