Abstract
The invention provides gastric residence systems with specifically tailored architectures and methods for making such systems. The components of the gastric residence systems can be manufactured by three-dimensional printing or by co-extrusion. The ability to construct precise architectures for the systems provides excellent control over drug release, in vivo stability, and residence time of the systems.
