The instant invention relates to a solid product comprising a liquidbiologically active agent which is intimately associated to a stabilizingagent; particularly a solid product that can be reconstituted to a clear,stable, stabilized nanodispersion or loaded micelles comprising a polymer as astabilizing agent and a liquid, preferably water immiscible, biologicallyactive agent. The instant invention is further directed toward a process forthe production of the above solid product ; particularly to micelles ornanodispersions produced by hydration of a cake or powder of the solidproduct, produced via an effective treatment of a stabilized solutioncomprising for example a polymer as a stabilizing agent, such as anamphiphilic block copolymer or a small molecular weight surfactant, loadedwith a liquid biologically active agent, such as propofol, an optionaladditive, and a suitable solvent.
