摘要： The invention relates to compositions and methods for drug delivery suitable for promoting the transmucosal absorption of drugs, especially drugs with poor intrinsic bioavailability, such as peptides, proteins, vaccines, and nucleic acids. The delivery system of this invention preferably comprises fatty acid esters and their hydrophilic derivatives that associate with water and other polar solvents to form reverse micelles tha are physically stabilized in the presence of gastrointestinal fluid, water, and other hydrophilic solvents. Such stable reverse micelles are formed by suitable mixtures of polymeric or non-polymeric compounds with amphiphiles. Micelles made using these methods undergo phase transformation more slowly resulting in delayed drug release profiles and sustained absorption. When administered as a pharmaceutical to mucosal surfaces following oral ingestion or intranasal administration, therapeutic molecules principally solubilized in the aqueous phase are protected from digestion by mucosal enzymes and other mucosal degradative processes and are taken up by absorptive cell mechanisms and reach appropriate body compartments. The reverse micelle compositions may comprise mono-, di-glycerides and/or their transesterifed products containing C6-C12 fatty acids chains, wherein the transester groups consist of hydrohilic moieties.
摘要翻译： 本发明涉及用于药物递送的组合物和方法，其适用于促进药物，特别是具有差的内在生物利用度的药物（例如肽，蛋白质，疫苗和核酸）的经粘膜吸收。 本发明的递送系统优选包含与水和其它极性溶剂缔合以形成反胶束的脂肪酸酯及其亲水性衍生物，其在胃肠液，水和其它亲水溶剂存在下物理稳定。 这种稳定的反胶束由聚合物或非聚合物与两亲物的合适混合物形成。 使用这些方法制备的胶束进行相变更慢，导致延迟的药物释放曲线和持续吸收。 当口服摄取或鼻内给药后作为药物施用于粘膜表面时，主要溶解在水相中的治疗分子被保护不被粘膜酶和其它粘膜降解过程消化，并被吸收细胞机制吸收并达到适当的身体隔室。 反胶束组合物可以包含含有C6-C12脂肪酸链的单 - ，二 - 甘油酯和/或其酯交换产物，其中酯基组由亲水部分组成。

摘要： The present invention relates generally to coated medical devices, preferably a stent, that has a drug-eluting surface completely or partially coated with a coating that comprises two or more forms of a biologically active material. In particular, the invention is directed to a coated medical device having a coating that comprises at least one polymer and a biologically active material that is present in at least two different forms. The coating may include more than one coating layer. Preferably, the coating is capable of releasing the different forms of the biologically active material in different amounts, at different rates, and/or at different time periods. The invention also relates to methods of making and methods of using the coated medical device.
