    • The present invention is directed to a method of reducing or preventing skin sensitization by inhibiting the immunological processing of a sensitizing drug as an antigen. The drug is sensitizing to humans, i.e., the drug is susceptible to inducing skin or mucosa sensitization in a human when the drug is transdermally administered to the human at a therapeutically effective rate. Skin sensitization reduction or prevention is induced by coadministering to the skin or mucosa of the human:(a) a therapeutically effective amount of a sensitizing drug, at a therapeutically effective rate over a predetermined period of time; and(b) an antigen processing-inhibiting agent in an amount effective to inhibit the antigen processing of the drug.The system of the invention comprises a matrix adapted to be placed in sensitizing drug and antigen processing-inhibiting agent transmitting relation to the selected skin or mucosa site. The matrix contains sufficient amounts of the drug and the agent to continuously coadminister to the skin or mucosa site the drug, at a therapeutically effective rate and over a predetermined delivery period, and the antigen processing-inhibiting agent, at a rate and for a period of time sufficient to inhibit the processing of the drug as an antigen.
    • 本发明涉及通过抑制作为抗原的敏化药物的免疫处理来减少或预防皮肤致敏的方法。 药物对人类敏感,即当药物以治疗有效的速率经皮给药时,药物易于引起人类皮肤或粘膜致敏。 通过向人的皮肤或粘膜共同诱导皮肤致敏减少或预防:(a)治疗有效量的敏化药物,以预定时间段的治疗有效速率; 和(b)有效抑制药物抗原加工的抗原加工抑制剂。 本发明的系统包括适于放置在致敏药物和抗原加工抑制剂中的基质,其与所选择的皮肤或粘膜部位传递关系。 基质含有足够量的药物和药剂,以治疗有效速率和超过预定的递送期间,以一定的速率和一段时间连续地连续地附着到皮肤或粘膜部位,药物,抗原加工抑制剂 的时间足以抑制作为抗原的药物的加工。
