  • Publication number: 20240226226
    Abstract: The present disclosure provides compositions, methods and kits for treatment of pruritus (itch) in an individual. The compositions, methods, and kits are for administering an implant comprising a kappa-opioid receptor agonist to an individual, where the implant comprises a sustained release composition comprising a kappa-opioid receptor agonist and a biocompatible polymeric matrix. Implantation of the device allows a controlled release of kappa-opioid receptor agonist for an extended period of time. The implant may be implanted subcutaneously in an individual in need of continuous treatment with a kappa-opioid receptor agonist for treatment and relief of pruritus.
