    • An eutectic composition having from (10) to (90) weight % of a first component comprising a pharmaceutically acceptable substituted C 6 -C 10 aryl compound wherein the aryl moiety includes a straight or branched moiety selected from the group consisting of C 1 -C 12 alkyl, C 1 -C 12 alkoxy, C 2 -C 6 alkanoyloxy, hydroxy, carboxy, carboxy substituted C 1 -C 12 alkyl and mixtures and isomers thereof. The composition also includes from (10) to (90) weight % of a second component comprising a water-soluble preparation of a fat-soluble vitamin. Also disclosed is a method for preparing the eutectic composition of the present invention. The method includes the steps of forming a mixture from a predetermined amount of the first component with a predetermined amount of the second component, heating the mixture to melt at least one of the components, and mixing the components to form an eutectic blend. In a preferred embodiment, the method further includes the step of cooling the eutectic blend.
    • 具有(10)至(90)重量%的包含药学上可接受的取代的C 6 -C 10芳基化合物的第一组分的共晶组合物,其中芳基部分包括 C 1 -C 12烷基,C 1 -C 12烷基,C 1 -C 12烷基,C 1 -C 12烷基,C 1 -C 12 - 烷氧基,C 2 -C 6烷酰氧基,羟基,羧基,羧基取代的C 1 -C 12烷基和 混合物和异构体。 组合物还包括(10)至(90)重量%的包含脂溶性维生素的水溶性制剂的第二组分。 还公开了制备本发明的共晶组合物的方法。 该方法包括以下步骤:用预定量的第二组分从预定量的第一组分形成混合物,加热混合物以熔化至少一种组分,并混合组分以形成共晶共混物。 在优选的实施方案中,该方法还包括冷却共晶共混物的步骤。
