The present invention provides the use of surface active proteins, especially class I and class II hydrophobins, in topically applied pharmaceutical formulations. The invention is particularly directed to topically applied pharmaceutical products for enhancing the penetration to achieve a transungual delivery of a prophylactically and/or therapeutically effective amount of an active ingredient (drug) to a patient (including animals and humans) into and/or through a nail, of the animal or human body, in order to treat one or more of a variety of diseases or disorders. Related embodiments of the invention are also disclosed.

Compositions, use and method for the use of surface active proteins in topical drug delivery across keratin

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.
