Abstract (en)

[origin: WO9956727A2] Self-emulsifying microemulsion or emulsion preconcentrate pharmaceutical compositions capable of forming an oil-in-water microemulsion or emulsion upon dilution with an aqueous solution are disclosed. The preconcentrate contains a therapeutically effective amount of a poorly water soluble therapeutic agent; a pharmaceutically effective amount of a low HLB oil component; and a surfactant system consisting essentially of at least one surfactant having an HLB of from about 10 to 20 and is substantially free or contains only minor amounts of a hydrophilic solvent system. Microemulsions or emulsions formed by diluting the self-emulsifying preconcentrate with an aqueous solution are also provided.
