  • Patent number: 8501215
    Abstract: 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.

  • Patent number: 7368126
    Abstract: Methods and compositions for systemically or locally administering a beneficialagent 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 prolonged duration of time. 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.

  • Publication number: 20070196415
    Abstract: 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.

  • Publication number: 20060193918
    Abstract: A nonaqueous, single-phase vehicle that is capable of suspending an active agent. The nonaqueous, single-phase vehicle includes at least one solvent and at least one polymer and is formulated to exhibit phase separation upon contact with an aqueous environment. The at least one solvent may be selected from the group consisting of benzyl benzoate, decanol, ethyl hexyl lactate, and mixtures thereof and the at least one polymer may be selected from the group consisting of a polyester, pyrrolidone, ester of an unsaturated alcohol, ether of an unsaturated alcohol, polyoxyethylenepolyoxypropylene block copolymer, and mixtures thereof. In one embodiment, the at least one solvent is benzyl benzoate and the at least one polymer is polyvinylpyrrolidone. A stable, nonaqueous suspension formulation that includes the nonaqueous, single-phase vehicle and an active agent, and a method of forming the same, are also disclosed.

  • Publication number: 20040109893
    Abstract: Drug delivery systems and kits are provided that release an anesthetic, such as bupivacaine, over a short duration. Methods of administering and preparing such systems are also provided. Drug delivery systems include a short duration gel vehicle and an anesthetic dissolved or dispersed in the gel vehicle. The gel vehicle comprises a low molecular weight bioerodible, biocompatible polymer and a water-immiscible solvent in an amount effective to plasticize the polymer and form a gel with the polymer. In some instances, a component solvent is used along with the water-immiscible solvent. An efficacy ratio, which is one way to measure the efficacy of a delivery system, can be controlled based on, for example, the construction of the gel vehicle to achieve a desired release profile.
