    • The present invention provides the hybrids wherein itraconazole, cyclosporine or carvedilol are intercalated into the interlayers and/or absorbed onto the surfaces of layered silicates. The hybrids according to the present invention enable the maximization of bioavailability of drugs by dissolving the drugs from the layered silicates. Furthermore, the present invention provides the preparing methods of the hybrids. The process comprises: (1) dispersing a layered silicate in an aqueous solution to form an aqueous solution containing the layered silicate; (2) dissolving a drug in a organic solvent to form an organic solution containing the drug, the organic solvent having a solubility higher than that in the aqueous solution; and (3) mixing and hybridizing in the inerrface of the aqueous solution containing the layered silicate and the organic phase solution containing the drug in order to intercalate the drug into the interlayers of the layered silicate and/or to absorb the drug onto the surface of the layered silicate.
    • 本发明提供了伊曲康唑,环孢菌素或卡维地洛插入中间层和/或吸收到层状硅酸盐表面上的杂交体。 根据本发明的杂交体能够通过从层状硅酸盐中溶解药物使药物的生物利用度最大化。 此外,本发明提供了杂种的制备方法。 该方法包括:(1)将层状硅酸盐分散在水溶液中以形成含有层状硅酸盐的水溶液; (2)将药物溶解在有机溶剂中以形成含有药物的有机溶液,所述有机溶剂的溶解度高于所述水溶液中的溶解度; 和(3)在含有层状硅酸盐的水溶液和含有药物的有机相溶液的表面中混合和杂交,以将药物插入层状硅酸盐的夹层中和/或将药物吸收到 层状硅酸盐。
