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 .
