  • Process for the preparation of amphiphilic poly (N-vinyl-2-pyrrolidone) block copolymers
    Patent number: 7262253
    Abstract: The instant invention provides a two-step polymerization process for preparing amphiphilic poly(N-vinyl-2-pyrrolidone), (PVP)-block-polyester copolymers and other diblock and triblock copolymers consisting of PVP as one block. The block copolymers of the invention can be used as vehicles for drug delivery.

  • Solid formulations of liquid biologically active agents
    Publication number: 20060198891
    Abstract: The instant invention relates to a solid product comprising a liquid biologically active agent which is intimately associated to a stabilizing agent; particularly a solid product that can be reconstituted to a clear, stable, stabilized nanodispersion or loaded micelles comprising a polymer as a stabilizing agent and a liquid, preferably water immiscible, biologically active agent. The instant invention is further directed toward a process for the production of the above solid product; particularly to micelles or nanodispersions produced by hydration of a cake or powder of the solid product, produced via an effective treatment of a stabilized solution comprising for example a polymer as a stabilizing agent, such as an amphiphilic block copolymer or a small molecular weight surfactant, loaded with a liquid biologically active agent, such as propofol, an optional additive, and a suitable solvent.
