    • Compositions and methods are provided for intranasal delivery of interferon-β yielding improved pharmacokinetic and pharmacodynamic results wherein the composition is free of a stabilizer that is a protein or a polypeptide. In certain aspects of the invention, the interferon-β is delivered to the intranasal mucosa along with one or more intranasal delivery-enhancing agent(s) to yield substantially increased absorption and/or bioavailability of the interferon-β and/or a substantially decreased time to maximal concentration of interferon-β in a tissue of a subject as compared to controls where the interferon-β is administered to the same intranasal site alone or formulated according to previously disclosed reports. The enhancement of intranasal delivery of interferon-β according to the methods and compositions of the present invention allows for the effective pharmaceutical use of these agents to treat a variety of diseases and conditions in mammalian subjects.
    • 提供组合物和方法用于鼻内递送干扰素-β,产生改善的药代动力学和药效学结果,其中组合物不含作为蛋白质或多肽的稳定剂。 在本发明的某些方面,将干扰素-β与一种或多种鼻内递送增强剂一起递送至鼻内粘膜,以产生干扰素-β的显着增加的吸收和/或生物利用度和/或基本上减少 与将干扰素-β单独施用于相同的鼻内部位或根据先前公开的报道配制的对照相比,在受试者组织中最大浓度的干扰素-β的时间。 根据本发明的方法和组合物增加干扰素-β的鼻内递送允许这些药剂的有效药物用途来治疗哺乳动物受试者中的各种疾病和病症。
