This document summarizes a seminar on gastroretentive drug shipping and delivery methods (GRDDS). GRDDS are built to retain medicine inside the stomach for extended periods of time to permit for sustained drug release. The seminar outlines different GRDDS systems like floating, swelling, mucoadhesive, and large density systems.
