the adhesive layer of the medical patch produced. The active substances tested were the salts of ibuprofen obtained by pairing the anion of ibuprofen with organic cations such as propyl esters of amino acids such as tyrosine, tryptophan, histidine, or phenylalanine. For comparison, the penetration of unmodified ibuprofen and commercially available patches was also tested. Acrylate copolymers based on
本研究旨在评估以离子对形式引入布洛芬的结构修饰对布洛芬通过皮肤的渗透性以及所生产的医用贴片粘合层特性的影响。测试的活性物质是通过将布洛芬的阴离子与有机阳离子(如酪氨酸、色氨酸、组氨酸或苯丙氨酸等氨基酸的丙酯)配对而获得的布洛芬盐。为了进行比较,还测试了未改性布洛芬和市售贴剂的渗透性。基于甲基丙烯酸异冰片酯作为生物成分的丙烯酸酯共聚物和增加 Tg(“硬”)的单体用于生产透皮贴剂的粘合层。根据粘合性能对获得的贴片进行表征,并测试活性成分的渗透性和活性成分通过皮肤的渗透性。本研究证明了开发基于丙烯酸的光反应性透皮贴剂的可能性,该贴剂含有可以提供治疗适当剂量布洛芬的生物成分。
