Abstract
Methods for modifying polypeptide agents to enhance their transdermal electrotransport flux are provided. The polypeptide is modified by reducing the potential of the polypeptide for forming .alpha.-helical or .beta.-sheet segments. In particular, amino acid residues known to stabilize .alpha.-helical and .beta.-sheet segments can be replaced with destabilizing residues and known helix breakers. Modified molecules and compositions including the molecules are also provided.
