  • Patent number: 11246963
    Abstract: Disclosed herein is a delivery composition for administering a hydrophobic active agent. In one embodiment, a delivery composition for local administration of a hydrophobic active agent to a tissue or organ of a patient is disclosed. In one embodiment, the delivery composition includes a cationic delivery agent, a therapeutically effective amount of a hydrophobic active agent and a pharmaceutically acceptable aqueous carrier. In one embodiment, the cationic delivery agent includes polyethyleneimine (PEI). In an embodiment, the invention includes a drug delivery device including a substrate; and coated therapeutic agent particles disposed on the substrate, the coated therapeutic agent particles comprising a particulate hydrophobic therapeutic agent; and a vinyl amine polymer. Methods of making the delivery composition, as well as kits and methods of use are also included herein.

  • Patent number: 8496954
    Abstract: Described are coating systems for the controlled delivery of hydrophilic bioactive agents, for example, from implantable medical devices. The coating systems of the invention comprise (a) a polymeric basecoat layer containing one or more hydrophilic bioactive agents; and (b) an elution-controlling topcoat layer that comprises a poly(ethylene-co-vinyl acetate) copolymer. The elution rate of the hydrophilic bioactive agent can be controlled by varying the vinyl acetate concentration in the elution-controlling topcoat layer.
