  • Short duration depot formulations
    Patent number: 8278330
    Abstract: 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.
    Type: Grant
    Filed: September 27, 2010
    Date of Patent: October 2, 2012
    Assignee: Durect Corporation

  • Controlled release depot formulations
    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.

  • Excipients in drug delivery vehicles
    Publication number: 20050281879
    Abstract: Injectable depot gel compositions and kits that provide an excipient for modulating a release rate and stabilizing beneficial agents are provided. Methods of administering and preparing such systems are also provided. The gel compositions comprise biodegradable, bioerodible polymers and water-immiscible solvents in amounts effective to plasticize the polymers and form gels with the polymers. Suitable excipients include pH modifiers, reducing agents, and antioxidants.
