电致孔下表面活性剂促进吡罗昔康的经皮渗透
摘 要:目的利用表面活性剂的促渗作用,提高脂溶性药物通过电致孔形成的水性通道的经皮渗透量.方法以吡罗昔康和不同浓度的非离子表面活性剂聚山梨酯80溶液为供给液,进行电致孔;改变脉冲参数和聚山梨酯80的浓度,通过体外透皮实验,考察这些因素的影响.结果当聚山梨酯80的浓度大于临界胶束浓度(cmc)时,吡罗昔康在电致孔下经皮渗透速率明显提高,在最佳条件下,较被动扩散提高了近50倍,但随聚山梨酯80的浓度增加仅略有提高;当聚山梨酯80的浓度低于cmc时,吡罗昔康的渗透速率明显降低.结论综合利用聚山梨酯80的促渗作用和电致孔时形成的水性通道,可以有效提高吡罗昔康的透皮量.
