Abstract

A dispensing device is disclosed for delivering a beneficial agent. The device comprises (1) a semipermeable housing defining a internal space, (2) an optional and presently preferred density member in the space, (3) a heat responsive composition comprising a beneficial agent in the space, (4) a space consuming member in the device, (5) a non-toxic compound blended with the heat responsive composition for enhancing its viscosity; (6) an exit port in the wall for increasing the internal pressure of the dispenser and for simultaneously letting the beneficial agent exit through said port from the device, and (7) an embodiment comprising a prehydrating fluid for fastening the start-up of delivery from the delivery system.
