ABSTRACT:
The present invention relates to an osmotically driven agent delivery system for delivering a beneficial agent. The osmotic delivery system includes an osmotic agent which operates by imbibing fluid from an outside environment, causing the release of a beneficial agent. The osmotic delivery system includes a liquid or gel additive surrounding the osmotic agent for enhancing start-up and lubricating the osmotic agent. The liquid or gel additive is an incompressible lubricating fluid which fills any air gaps between the osmotic agent and the walls of a chamber and substantially reduces start-up delays.
