A drug held or supported by an interface comprising a porous matrix is dissolved with a drug dissolution liquid containing a humectant, and the drug is transdermally delivered by iontophoresis. The humectant includes e.g. glycerin and other polyhydric alcohols, sugar alcohols, proline and other amino acids and acidic mucopolysaccharides. The concentration of the humectant may be about 1 to 50% by weight, and the concentration of proline or other amino acid or its salt may be about 1 to 30% by weight. The drug includes (1) a physiologically active peptide or protein with a molecular weight of 100 to 30,000 or (2) a nonpeptide physiologically active compound with a molecular weight of 100 to 1,000.
用含有保湿剂的药物溶解液溶解由多孔基质构成的界面保持或支撑的药物,并通过离子透入疗法透皮给药。保湿剂包括甘油和其他多元醇、糖醇、脯氨酸和其他氨基酸以及酸性粘多糖等。保湿剂的浓度按重量计约为 1%至 50%,脯氨酸或其他氨基酸或其盐的浓度按重量计约为 1%至 30%。药物包括(1)分子量为 100 至 30,000 的生理活性肽或蛋白质,或(2)分子量为 100 至 1,000 的非肽生理活性化合物。
