脂质体(Iiposome)是由天然磷脂分散在水中形成的比较稳定的双分子膜的超微型球状载体制剂。由于它具有一个立体结构系统,使药物能被保护在很好的空间里,近年来把脂质体作为药物载体,如抗肿瘤药、抗生素、酶、激素、蛋白质等都可以制成脂质体应用。然而,脂质体在制剂学领域中尚属一个待开发的新剂型,许多研究论文都认为脂质体不宜用加热灭菌的办法,这是影响脂质体广泛应用于临床的一个重要因素,所以国外都采用无菌操作法进行制备的。目前国内对它的灭菌方法也正在进行探讨, Liposomes (Iiposome) is a relatively stable bilayer membrane formed by the dispersion of natural phospholipids in water. Because of its three-dimensional structure system, the medicine can be protected in a very good space. In recent years, liposomes can be made into liposomes as drug carriers such as antineoplastics, antibiotics, enzymes, hormones and proteins application. However, liposomes in the field of pharmaceutics is still to be developed a new dosage form, many research papers that liposomes should not be used heat sterilization method, which is widely used in liposomal clinical application of an important factor, Therefore, foreign countries are using aseptic method for preparation. At present, its sterilization method is also being explored,
