    摘要： Injectable depot compositions are provided that include a polymer matrix having a plurality of bioerodible, biocompatible polymers wherein each polymer of the plurality of polymers has a specified average molecular weight, and the polymer matrix has a broad molecular weight distribution of the plurality of polymers; a solvent having a miscibility in water of less than or equal to 7 wt % at 25° C., in an amount effective to plasticize the polymer and form a gel therewith; and a beneficial agent. The compositions have substantially improved shear thinning behavior and reduced injection force, rendering the compositions readily implanted beneath a patient's body surface by injection.

    摘要： Methods and compositions for systemically or locally administering a beneficial agent to a subject are described, and include, for example, implantable elastomeric depot compositions that can be injected into a desired location and which can provide controlled release of a beneficial agent over a prolonged duration of time. The compositions include a biocompatible, elastomeric caprolactone copolymer, a biocompatible solvent having low water miscibility that forms an elastomeric viscous gel with the polymer and limits water uptake by the implant, and a beneficial agent.

    摘要： Injectable depot compositions with dual mechanisms of release rate control are provided for sustained beneficial agent delivery in a patient. The composition includes bioerodible particles and an injectable depot vehicle containing a bioerodible polymer in an organic solvent, for forming a bioerodible depot implant after administration to the patient. The bioerodible particles are dispersed in the depot vehicle and contain a beneficial agent and a release rate controlling agent retarding the release of the beneficial agent from the bioerodible particles and from the depot implant.
