    • The invention relates to a lipid particle forming matrix, characterized by, that from a defined system of at least two lipid components chosen from classes of different polarity, in which at least one of the lipid components is bilayer forming, discrete lipid particles are formed spontaneously when interacting with aqueous systems. Preferably at least one of the lipid components is amphiphatic and polar and one is nonpolar. These discrete particles are formed spontaneously from the matrix without any chemical or physical treatment or initiation. The lipid particle forming matrix can contain bioactive materials, chosen from the group of drugs, herbicides, pesticides, fertilizers, food and cosmetic ingredients or additives. The invention also relates to a process for the production of the matrix, the use of the lipid particle forming matrix as a carrier system for bioactive materials and pharmaceutical composition such as oral, rectal, nasal, vaginal, ocular or parenteral vehicles, creams, ointments, capsules and tablets containing the said lipid particle forming matrix and a drug.
    • 本发明涉及形成脂质颗粒的基质,其特征在于,从至少两种选自不同极性类别的脂质组分的确定体系中,其中至少一种脂质组分是双层形成的,离散的脂质颗粒自发形成 当与含水体系相互作用时。 优选地,脂质组分中的至少一种是双脂族和极性的,一个是非极性的。 这些离散的颗粒是从基质自发形成的,没有任何化学或物理的处理或引发。 脂质颗粒形成基质可以含有选自药物,除草剂,杀虫剂,肥料,食品和化妆品成分或添加剂的生物活性物质。 本发明还涉及生产基质的方法,使用脂质形成基质作为生物活性物质的载体体系和药物组合物如口服,直肠,鼻,阴道,眼或肠胃外的赋形剂,霜剂,软膏 ,含有所述脂质形成基质的胶囊和片剂和药物。
