Orally administrable polymer-carrying units for expanding in a stomach of a mammal to fill a space in the stomach, the polymer-carrying units including: a carrier; a plurality of polymer molecules expandable in aqueous solutions, releasably coupled to the carrier; and means for selectively decoupling the polymer molecules from the carrier so that the polymer molecules and carrier are released in the stomach, are provided.

主权项

1. An orally administrate polymer-carrying unit for expanding in a stomach of a mammal to fill a space in the stomach and deliver at least one active agent thereto, the polymer-carrying unit comprising:
(a) a carrier having at least one outer surface; (b) at least one coupling member having a first surface and a second surface; (c) a plurality of polymer molecules, expandable in the presence of an aqueous solution, associated with the first surface of the coupling member; (d) a coupler releasably coupling the second surface of the coupling member to the outer surface of the carrier; and (e) a decoupler arranged for selectively decoupling the coupling member from the carrier; and (f) an active agent releasably associated with the carrier, the coupling member, the polymer molecules, or a combination thereof.
