Abstract
Methods and compositions for systemically or locally administering by implantation a beneficial agent to a subject are described, and include, for example, compositions having burst indices of 8 or less for systemic applications and systems releasing 10% or less of the total dose of beneficial agent in the first 24 hours after implantation for local applications. The compositions include a biocompatible polymer, a biocompatible solvent having low water miscibility that forms a viscous gel with the polymer and limits water uptake by the implant, and a beneficial agent.
