摘要:
The present invention generally relates to reducing the mucoadhesive properties of a particle. In some embodiments, the particle is coated with and/or associated with a (poly(ethylene glycol))- (poly(propylene oxide))-(poly(ethylene glycol)) triblock copolymer. Methods for preparing inventive particles using a poly(ethylene glycol)-vitamin E conjugate as a surfactant are also provided. In some embodiments, methods are provided comprising administering to a subject a composition of particles of the present invention. Such particles with reduced mucoadhesive properties are useful in delivering agents to mucosal tissues such as oral, ophthalmic, gastrointestinal, nasal, respiratory, and genital mucosal tissues.
摘要(中):
本发明一般涉及降低颗粒的粘膜粘附性质。 在一些实施方案中,颗粒用(聚(乙二醇)) - (聚(环氧丙烷)) - (聚(乙二醇))三嵌段共聚物涂覆和/或与其相连。 还提供了使用聚(乙二醇) - 维生素E缀合物作为表面活性剂制备本发明颗粒的方法。 在一些实施方案中,提供了包括向受试者施用本发明颗粒组合物的方法。 具有降低的粘膜粘附性质的这种颗粒可用于将药物递送至粘膜组织如口服,眼科,胃肠道,鼻腔,呼吸道和生殖器粘膜组织。
