脂质体作为药物载体具有提高药物疗效、减轻药物不良反应及靶向作用的特点,常用制备方法主要有薄膜分散法、逆相蒸发法、注入法、超声波分散法等。在制备含药脂质体时,根据药物被装载的机理不同,又可分为被动载药法(passive loading)与主动载药法(active loading)两大类。传统 Liposomes as drug carriers have the characteristics of improving drug efficacy, alleviating adverse drug reactions and targeting effects. The commonly used preparation methods include thin film dispersion method, reverse phase evaporation method, injection method and ultrasonic dispersion method. In the preparation of drug-containing liposomes, according to the mechanism of drug loading is different, can be divided into passive loading (active loading) and active loading (active loading) two categories.
