Abstract
Gastric residence systems comprising therapeutic agent formulations for sustained gastric release of therapeutic agents are disclosed, as well as methods for using such systems. The systems are characterized by use of a dispersant in the formulations, which improves the burst release characteristics and long-term release rate characteristics of the systems. Milling of therapeutic agent can also be performed to prepare agent particles of desired size.
