    • The present invention relates to formulations and methods for the mucosal and parenteral administration of lipid particles and suspensions. The formulations of this invention are stable lipid particles useful for oral delivery of water-insoluble therapeutic agents, vaccines and diagnostics. The compositions of this invention promote the mucosal absorption of biologically active molecules across mucosal epithelial barriers. Stabilization of lipid particles is achieved by coating the hydrophobic central core with a polymer shell. The polymer shell can include bioadhesive agents, ligands, and absorption promoting agents. This invention relates to oral drug delivery systems for hydrophobic drugs, and in particular is concerned with improving the bioavailability of hydrophobic drugs from such systems. Using this system, anticancer drugs such as taxanes are orally effective.
    • 本发明涉及用于脂质颗粒和悬浮液的粘膜和肠胃外给药的制剂和方法。 本发明的制剂是用于口服递送水不溶性治疗剂,疫苗和诊断剂的稳定的脂质颗粒。 本发明的组合物促进跨越粘膜上皮屏障的生物活性分子的粘膜吸收。 脂质颗粒的稳定化通过用聚合物壳包覆疏水中心核来实现。 聚合物壳可以包括生物粘附剂,配体和吸收促进剂。 本发明涉及用于疏水性药物的口服药物递送系统,并且具体涉及提高来自这种系统的疏水性药物的生物利用度。 使用此系统,抗癌药物如紫杉烷口服有效。
