GASTRORETENTIVE CONTROLLED RELEASE VEHICLES THAT INCLUDE ETHYLENE COPOLYMERS, ETHYL CELLULOSES, AND/OR THERMPOPLASTIC POLYURETHANES

摘要

Gastroretentive controlled release vehicles may, in some embodiments, (1) comprise a polymeric matrix and agents for the treatment, prevention, and/or mitigation of a disease and/or side effect thereof and (2) have both gastroretentive properties and controlled release properties. Preferrably, the polymeric matrix may comprise ethylene copolymers, ethyl celluloses, and/or thermoplastic polyurethanes that may optionally be partially crosslinked.
