透皮吸收的药物剂型有搽剂、洗剂、涂布剂、气雾剂、粉剂、油膏、软膏、霜剂、橡皮膏等,其品种之多、数量之大,堪与口服、注射剂相提并论。但因疗效不突出、研究不深入,应用亦不够广泛。近年来,随着透皮吸收作用机制和制药技术的深入研究,新颖的长效、高效透皮吸吸药物制剂相继出现,这些制剂不仅疗效好,用药安全,且较口服、注射用药方便得多,引起了国内外药学界的广泛重视,如东莨菪碱硬膏、硝酸甘油缓释膏布、消炎痛橡皮膏、长压定PATCH等。
Transdermal absorption of drug formulations are liniment, lotion, coating agent, aerosol, powder, ointment, ointment, cream, plaster and so on, its variety of large, large number, worthy of oral, injection compared . However, due to curative effect is not prominent, the study is not in-depth, the application is not broad enough. In recent years, with the percutaneous absorption mechanism and in-depth study of pharmaceutical technology, novel long-acting, high-performance transdermal absorption drug preparations have emerged, these preparations not only efficacy, medication safety, and more convenient than oral and injectable drugs , Aroused widespread attention at home and abroad pharmacy community, such as scopolamine plaster, nitroglycerin sustained-release paste cloth, indomethacin adhesive plaster, such as long-pressure fixed PATCH.
