  Methods and compositions for systemically or locally administering by implantation a beneficial agent to a subject are described, and include, for example, depot gel compositions that can be injected into a desired location and which can provide controlled release of a beneficial agent over a short duration of time. The compositions include a low molecular weight 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.

  本文描述了系统性或局部通过植入给予有益药物的方法和组合物，其中包括例如可注射到所需位置的储库凝胶组合物，可以在短时间内提供有益药物的控制释放。该组合物包括低分子量生物相容性聚合物、生物相容性溶剂，具有低水溶性，与聚合物形成黏稠的凝胶，并限制植入物的吸水性，以及有益药物。
