    • In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful selection of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry powder comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.

    • In accordance with the present invention, there are provided stabilized total nutrient admixture (TNA) compositions which are useful for the in vivo parenteral delivery of pharmacologically acceptable lipids or fats, as well as methods for the preparation thereof. In particular, the pharmacologically acceptable lipid or fat is contained within a protein walled shell. In a particular embodiment of the invention, a TNA composition using human serum albumin (HSA) as a stabilizer has been prepared as a convenient three-in-one formulation (i.e., containing a fat emulsion, dextrose, and amino acids plus electrolytes). This “three-in-one” formulation can be prepared in liquid form or in dry form (comprising submicron-sized nanoparticles). The dried material is stable, even under long term storage, and is easily reconstituted immediately before use by simply adding sterile water (with or without vitamin supplementation) This serves to rehydrate the powder into a TNA suitable for injection. The long shelf life, ease of reconstitution, and single-component injectability of invention compositions provide significant cost savings, as such compositions can be reconstituted and administered safely, even in the home. In addition, HSA, the stabilizing agent of choice for use in the practice of the present invention, has been shown to improve survival and wellness when given as a supplement to patients receiving conventional forms of total nutrient admixtures.
    • 根据本发明,提供了可用于体内胃肠外递送药理学上可接受的脂质或脂肪的稳定的总营养混合物(TNA)组合物,以及其制备方法。 特别地,药理学上可接受的脂质或脂肪包含在蛋白质壁壳内。 在本发明的一个具体实施方案中,已经制备了使用人血清白蛋白(HSA)作为稳定剂的TNA组合物作为方便的三合一制剂(即,含有脂肪乳剂,葡萄糖和氨基酸加电解质)。 这种“三合一”制剂可以以液体形式或干燥形式(包括亚微米尺寸的纳米颗粒)制备。 干燥的材料即使在长期储存下也是稳定的,并且在使用前立即通过简单地加入无水(有或没有补充维生素)容易地重构,用于将粉末再水合成适合注射的TNA。 本发明组合物的长保存期限,易于重构和单组分可注射性提供显着的成本节约,因为即使在家中也可安全地重构和施用这些组合物。 此外,HSA是用于本发明实践的选择的稳定剂,已经显示出,当给予作为补充常规形式的总营养混合物的患者时,HSA可改善存活和健康。
