摘要: 本文考察了某些渗透促进剂如月桂氮(AZ)、油酸(OA)、泊洛沙姆(POL)和丙二醇(PG)等对胰岛素体外经皮离子导入渗透性的影响。结果表明AZ对离子导入具有协同作用, PG能够增强这种作用, 三者并用对胰岛素的经皮渗透具有特别显著的促渗效果。5%AZ/PG与离子导入并用后, 较单独离子导入处理组的促渗因子为2.75OA不能增强离子导入的作用。离子导入与某些渗透促进剂并用为胰岛素等大分子多肽类药物的透皮给药提供了新的思路和可能。

Abstract: The effects of some commonly used penetration enhancers such as laurocapram (AZ), oleic acid (OA), poloxamer (POL) and propylene glycol (PG) on the in vitro transdermal iontophoretic delivery of insulin through full-thickness mouse skin were investigated. The results showed that AZ had a synergistic effect on iontophoretic ability to enhance skin permeation of insulin, and PG could further increase this effect. 5% AZ / PG increased the iontophoretic steady state flux of insulin by a factor of 2.75 compared to that treated with iontophoresis alone. OA did not further enhance iontophoretic effect to increase skin permeation of insulin. The combination of iontophoresis and some enhancer provided a novel idea and possibility for transdermal delivery of insulin.
