The invention discloses peptides and proteins for iontophoretic delivery.
Specifically disclosed are methods for iontophoretic delivery of assemblages of amino acids which comprises modifying said assemblages of amino acids to an isoelectric point less than about 4.0 or greater than about 7.3 with an electrostatic charge of plus or minus 1 and patches with assemblages of amino acids with isoelectric points less than about 4.0 or greater than about 7.3 with an electrostatic charge of plus or minus 1.
