Methods and compositions for systemic or topical administration by implantation of a useful agent to a subject are described, which may, for example, be injected at a desired location and provide controlled release of the useful agent over a short period of time. Storage gel compositions that may be used. The composition comprises a low molecular weight biocompatible polymer, a biocompatible solvent and a useful agent that form a viscous gel with the polymer and have a low water miscibility that limits water absorption by the implant. |
