It may be useful to enhance the transdermal delivery of the polypeptide by adding an aqueous cosolute/cosolvent with negative Setschenow constants. The electrolytic device preferably comprises a hydrophilic reservoir containing a supply of the aqueous polypeptide solution or suspension, an electric battery, two extended contacts, and optionally a semipermeable membrane between the reservoir and the patient's skin. Representative polypeptides include oxytocin, angiotensin I, II, and III, substance P, vasopressin, lypressin, desmopressin, leuprolide acetate, antripeptin, and the like.
