Abstract: This invention relates to a novel formulation for fat-soluble drugs which self-emulsify in the presence of an aqueous medium with little agitation. More specifically, the invention is concerned with the formulation of a new dosage form for fat-soluble drugs in the form of a soft-gelatin capsule which forms emulsion instantly when the contents are released and mixed with gastrointestinal fluid. The formulation comprises a suitable mixture of drug with an appropriate oil and an appropriate surfactant system.
