摘要
局部用药比其他途径有一些优势;该药物可在解剖区给予治疗,限制全身分布和副作用。然而,皮肤的结构使它成为药物渗透的高效屏障。在克服这一障碍的策略中,脂质体是一种令人关注的载体,用于将药物输送到皮肤、滑膜腔或其他炎症或退行性疾病影响的区域。脂质体是由磷脂双分子层形成的纳米尺寸的脂质体载体。它们具有制备可行性和可携带脂质和/或水生化合物的生物相容性等优点,已广泛应用于各种药物给药系统中,用于药物靶向、控释和增强药物渗透性。传统的脂质体不太稳定,局部应用后不适合在皮肤上给药,因为脂质层僵硬,脂质体在皮肤表面积累,脱水,最终碎裂。与此同时也出现了其他的剂型,如转移体、核小体或醇小体。目前的工作是对已发表的关于开发脂质体制剂(该制剂含有缓解炎症和退行性疾病的症状的非甾体抗炎药)的科学论文进行综述。概述了脂质体类型、组成、制备方法、脂质体特征、外用溶剂、进行的体外渗透研究、进行的体内抗炎试验以及在过去五年中发表的不同研究中获得的结果。
