  • Self-emulsifying active substance formulation and use of this formulation
    Patent number: 8197829
    Abstract: The present invention relates to self-emulsifying formulations based on an active ingredient component and a formulation base with a lipid component and with a binder component and to the use of this formulation as dosage form in the life science sector.
