    • The invention relates to a use of surface active hydrophobins for applications in pharmaceutical technology, in particular as excipients for galenic use. Provided is a method for either admixture of hydrophobins to galenic compositions or for treating the surface of pharmaceutical forms with a hydrophobin-containing solution to modify the pharmaceutical properties of the galenic form. In a preferred embodiment of the invention hydrophobins are used to improve the properties of a pharmaceutical composition, e.g. to act as a surfactant or to increase resistance to disintegration of the galenic forms to achieve a retarded drug release. The galenic form to be modified by the use of surface active proteins as excipients can be capsules, tablets, pills, microparticles, vesicles, and suppositories, although further galenic forms are envisioned. The surface active proteins used for the purpose of present invention can either be isolated from their respective natural source or prepared by recombinant techniques and expression in a suitable host.
    • 本发明涉及用于制药技术中的表面活性疏水蛋白的用途,特别是作为涂覆液使用的赋形剂。 提供了将疏水蛋白与盖仑组合物混合或用含疏水蛋白的溶液处理药物形式的表面以改变盖仑膜形式的药物性质的方法。 在本发明的优选实施方案中,疏水蛋白用于改善药物组合物的性质,例如, 作为表面活性剂或增加耐受霜冻形式的崩解以实现延缓药物释放。 通过使用表面活性蛋白质作为赋形剂来修饰的盖仑形式可以是胶囊,片剂,丸剂,微粒,囊泡和栓剂,尽管可以预见到更多的盖仑制剂形式。 用于本发明目的的表面活性蛋白质可以从其各自的天然来源分离或通过重组技术制备并在合适的宿主中表达。
